                            ORDER AND JUDGMENT *

     *
              This Order and Judgment is not binding precedent, except under the
                                                                    (continued...)
Before KELLY, HOLMES, and McHUGH, Circuit Judges.


      Until 2012, the Santa Fe National Forest was generally open to motorized

use. However, recognizing the detrimental impact of motor vehicles on national

parks and forests, the United States Forest Service (“Forest Service”) adopted a

nationwide rule requiring that only specific roads and trails on national forest

land be designated for motorized use in accordance with various environmental

and recreational criteria. The Forest Service then began the designation process

for the Santa Fe National Forest, and, pursuant to the National Environmental

Policy Act of 1969 (“NEPA”), 42 U.S.C. §§ 4321–47, it published an

Environmental Impact Statement (“EIS”) detailing the environmental effects of

various alternative route systems it was considering. Ultimately, the Forest

Service selected an alternative that significantly reduced the routes available for

motorized use.

      The New Mexico Off-Highway Vehicle Alliance (“NMOHVA”) petitioned

for review of the agency’s decision, alleging that the EIS failed to comply with



      *
       (...continued)
doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,
however, for its persuasive value consistent with Federal Rule of Appellate
Procedure 32.1 and Tenth Circuit Rule 32.1.



                                          2
NEPA in various ways. The district court upheld the agency’s action, finding that

it was not arbitrary or capricious. NMOHVA now appeals. Exercising

jurisdiction under 28 U.S.C. § 1291, we conclude that NMOHVA failed to

establish standing. Consequently, we dismiss this appeal and remand the case to

the district court with instructions to vacate its judgment and dismiss the case

without prejudice for lack of subject-matter jurisdiction.

                                          I

                                         A

      The Santa Fe National Forest, located in northern New Mexico,

encompasses over 1.5 million acres of land. Prior to 2012, fifty-three percent of

the forest’s total area remained presumptively open for motorized use. This

meant that people could “drive where they like[d] as long as no sign or closure

order post[ed] [the route] closed.” Aplt.’s App. at 90 (Final Envtl. Impact

Statement, prepared June 2012). Under this “open-use” regime, many visitors

created their own routes on the forest “by driving repeatedly in the same tracks.”

Additionally, some roads maintained by the Forest Service, but

officially closed to motorized use, were nonetheless being driven on.

      In 2005, the Forest Service promulgated a nationwide Travel Management

Rule (“TMR”) to address the growing impact of unmanaged motor vehicle use on

forest land. See Travel Management; Designated Routes and Areas for Motor

Vehicle Use, 70 Fed. Reg. 68,264 (Nov. 9, 2005) (codified at 36 C.F.R. §§

                                         3
212.50–212.57). The TMR requires the designation of specific routes for

motorized use, and prohibits driving on roads and trails not listed on maps

published by the agency. See 36 C.F.R. § 261.13. In choosing which routes

remain open, the Forest Service must consider, inter alia, the “effects on . . .

natural and cultural resources, public safety, provision of recreational

opportunities, access needs, [and] conflicts among uses.” 

More

specifically, the agency is directed to:

             consider effects on the following, with the objective of
             minimizing:

             (1) Damage to soil, watershed, vegetation, and other forest
             resources;

             (2) Harassment of wildlife and significant disruption of wildlife
             habitats;

             (3) Conflicts between motor vehicle use and existing or proposed
             recreational uses of National Forest System lands or neighboring
             Federal lands; and

             (4) Conflicts among different classes of motor vehicle uses of
             National Forest System lands or neighboring Federal lands. . . .

                                           B

      In accordance with the nationwide TMR, the Forest Service began the

process of developing a travel plan for the Santa Fe National Forest in 2006. As

part of this project, under NEPA, the agency was required to issue an EIS

providing “a detailed statement” of “the environmental impact of the proposed

                                           4
action” and “alternatives to the proposed action.” 42 U.S.C. § 4332(C); see 

EIS for “major Federal actions significantly affecting the quality of

the human environment”); see also 36 C.F.R. § 212.52(a) (requiring that

opportunities for public comment on proposed designations be given “consistent

with agency procedures under the National Environmental Policy Act”). The EIS

would compare the potential courses of action being considered by the Forest

Service against “the alternative of no action,” 40 C.F.R. § 1502.14(d), which

would reflect “‘no change’ from [the] current management direction or level of

management intensity,” Forty Most Asked Questions Concerning CEQ’s National

Environmental Policy Act Regulations, 46 Fed. Reg. 18,026, 18,027 (Mar. 23,

1981) (codified at 40 C.F.R. §§ 1500–08); 1 see also 40 C.F.R. § 1502.14 (stating

that the agency “should present the environmental impacts of the proposal and the

alternatives in comparative form, thus sharply defining the issues and providing a

clear basis for choice”).

      To comply with its NEPA obligations, the Forest Service published a final

EIS for the Santa Fe National Forest designation process in June 2012. The

agency defined the purpose of the project as (1) compliance with the TMR, and

(2) a reduction in the “detrimental effects to natural and cultural resources from

Cir. 2009).

                                          5
unmanaged motorized use and the existence of roads and motorized trails.”

Aplt.’s App. at 83. In constructing the “no-action alternative,” the agency found

that its database of available routes in the forest was inadequate because, under

the open-use regime, it had not kept a detailed record of roads and trails. For

example, while it attempted to conduct an inventory using aerial photographs in

1992, this process proved over-inclusive: “fence lines and other features that

appeared to be roads” were counted as roads, and no follow-up verification was

conducted. Aplee.’s Suppl. App. at 36 (Travel Analysis Process Report, prepared

June 2008). At one point, the Service estimated that “between 10 percent and 20

percent of the roads in [its] database [did] not exist.” 

Further, the

“unauthorized” 2 routes that visitors to the forest had created were “not tallied in

the forest’s database,” and the Service did not “have an inventory of all the

unauthorized roads in the forest.” Aplt.’s App. at 162.

      Thus, the agency concluded that its existing data did not “capture hundreds

of existing roads and trails,” Intervenors-Aplees.’ Suppl. App. at 48 (Defining the

Existing Condition: Should it be reality-based or INFRA-based?), and included

routes that no longer existed on the ground. To remedy this problem, the Forest


      2
             The term “unauthorized” is drawn from the TMR, see, e.g., Aplt.’s
App. at 424, and is used throughout the EIS to describe user-created routes.
Generally speaking, these routes are not illegal; indeed, many have been created
by motorized users in areas where driving off-road is allowed. We use the terms
“unauthorized” and “user-created” interchangeably throughout this order and
judgment.

                                           6
Service decided to pursue a “reality-based,” 

where motorized use

was actually occurring under the status quo regime, based on preexisting data,

field visits, sampling and statistical calculations, and input from motorized

vehicle users. The agency ultimately defined the no-action alternative as “the

forest’s best estimate of where people drive now, which reflects the current

management and present course of action.” Aplt.’s App. at 97. In a table, it

provided both the “total miles” of routes where driving was technically allowed

under the open-use policy and its calculation of the “miles being driven on.” 

These two figures—7,832 miles and 5,626 miles,

respectively—were also presented in Appendix 2 of the EIS, which compared the

miles of available routes under each of the various alternatives considered.

      The Forest Service then engaged in a detailed comparison of five

alternative route systems, each of which highlighted a different regulatory goal.

For example, Alternative 3 emphasized resource protection, Alternative 4

prioritized motorized access, and Alternative 5 focused on reducing conflicts

between motorized and non-motorized users. Alternative 2M, a version of

Alternative 2 that was modified to reflect public comments, represented the

agency’s “preferred alternative.” 

The EIS also discussed eighteen

other alternatives that the agency dismissed without detailed consideration

because they did not achieve the purpose of the project.




                                          7
      Based on the analysis contained in the EIS, the Forest Service issued a

Record of Decision (“ROD”) selecting Alternative 2M, which limited the use of

motor vehicles to 2,255 miles of roads, 208 miles of trails, and 41 acres for cross-

country travel. However, seventy miles of these roads—mainly “unauthorized

and closed forest system routes”—were not designated on the first motor vehicle

use map issued by the agency because they crossed the habitat of the Jemez

Mountains Salamander (“salamander”), a threatened species. Aplt.’s App. at 358

(Final Envtl. Impact Statement, prepared June 2012). The Forest Service stated

that it planned to conduct site-specific surveys to mitigate the impacts of these

roads on the salamander. If the adverse effects to the species or its habitat

created by a particular route could not be avoided, however, the route would not

be designated.

                                         C

      NMOHVA “is a statewide nonprofit alliance of motorized off-highway

vehicle enthusiasts and organizations” whose mission “is promoting, protecting

and preserving responsible off-highway recreation.” Aplt.’s Opening Br. at 4.

NMOHVA participated in the Santa Fe National Forest designation process,

suggesting various routes for inclusion, and submitting comments regarding the

Forest Service’s EIS analysis. After the Forest Service selected Alternative 2M,

NMOHVA pursued an unsuccessful administrative appeal of the agency’s

decision. In its petition, NMOHVA claimed that (1) the agency had failed to

                                         8
include a true no-action alternative because the estimated-use calculation omitted

approximately two thousand miles of available routes, (2) the range of

alternatives analyzed in the EIS was too narrow, (3) the agency’s scientific

analysis was based on flawed or unsupported assumptions, and (4) the failure to

list a bulk of the trails in the salamander’s habitat was arbitrary.

      After briefing from the parties and certain intervening environmental

groups (“Intervenors”), 3 and a hearing, the district court denied the petition,

concluding that the agency’s EIS analysis was not arbitrary and capricious. This

appeal followed.

                                          II

      On appeal, NMOHVA challenges four aspects of the Forest Service’s EIS:

(1) its construction of an estimated-use no-action alternative; (2) the range of

alternatives it considered; (3) its scientific analysis of the environmental impacts

of the various alternatives; and (4) its decision to withhold designation of routes

crossing the salamander’s habitat. At the outset, however, we must address the

Intervenors’ argument that NMOHVA lacks standing—and therefore that we lack

jurisdiction. See W. Energy All. v. Salazar, 

, 1046 (10th Cir. 2013)

(“[J]urisdiction is a threshold question which an appellate court must resolve


      3
             In a previous appeal in this case, we concluded that the Center for
Biological Diversity, WildEarth Guardians, and the Sierra Club had a right to
intervene under Federal Rule of Civil Procedure 24(a)(2). N.M. Off-Highway
Vehicle All. v. U.S. Forest Serv., 540 F. App’x 877, 882 (10th Cir. 2013).

                                           9
before addressing the merits of the matter before it.” (alteration in original)

(quoting Timpanogos Tribe v. Conway, 

, 1201 (10th Cir. 2002))).

Our standing inquiry proves dispositive: we conclude that NMOHVA does not

have standing; accordingly, we dismiss this appeal and remand the case to the

district court with instructions to vacate its judgment and to dismiss NMOHVA’s

action without prejudice for lack of jurisdiction.

                                          A

      The Intervenors allege that “NMOHVA has not proven that it has standing

to pursue this litigation.” Intervenors’ Br. at 13. The district court found that

NMOHVA’s standing affidavit was too vague to establish a concrete injury, but

nevertheless concluded that NMOHVA had demonstrated standing “by the

slimmest of margins” based on the administrative record and representations made

at a hearing. Aplt.’s App. at 33 (Mem. Op. & Order Den. Pet. for Review of

Agency Action, filed July 25, 2014). Our review of the district court’s standing

determination is de novo. See S. Utah Wilderness All. v. Palma, 

,

1152 (10th Cir. 2013). “If the district court lacked jurisdiction, ‘we have

jurisdiction on appeal, not of the merits but merely for the purpose of correcting

the error of the lower court in entertaining the suit.’” Estate of Harshman v.

Jackson Hole Mountain Resort Corp., 

, 1163 (10th Cir. 2004)

(citations omitted). After carefully examining the extensive record, we are

constrained to conclude that the district erred in finding standing. Importantly, as

                                          10
explicated below, NMOHVA had the burden to establish standing, and we

conclude that it failed to do so.

                                            1

      The jurisdiction of the federal courts is limited by Article III of the

Constitution to actual “cases” and “controversies.” U.S. Const. art. III, § 2, cl. 1.

“The doctrine of standing is one of several doctrines that reflect this fundamental

limitation.” Summers v. Earth Island Inst., 

, 493 (2009); accord

Habecker v. Town of Estes Park, 

, 1223 (10th Cir. 2008); see Ctr.

for Law & Educ. v. Dep’t of Educ., 

, 1156–57 (D.C. Cir. 2005)

(“We ascertain whether or not the matter before us is a ‘case’ or ‘controversy’ by

looking to whether, inter alia, the litigants have ‘standing.’” (citation omitted));

see also Kiser v. Reitz, 

, 606 (6th Cir. 2014) (“The standing doctrine

delineates the boundary between justiciable cases and controversies and those

disputes that are not appropriately resolved through judicial process.”). Under the

standing doctrine, we may only hear a case where a party can demonstrate that “it

has suffered a concrete and particularized injury that is either actual or imminent,

that the injury is fairly traceable to the defendant, and that it is likely that a

favorable decision will redress that injury.” Massachusetts v. EPA, 

,

517 (2007); accord Greenbaum v. Bailey, 

, 1243 (10th Cir. 2015).

      Moreover, “[s]ince federal courts are courts of limited jurisdiction, we

presume no jurisdiction exists absent an adequate showing by the party invoking

                                           11
federal jurisdiction.” Dutcher v. Matheson, 

, 985 (10th Cir. 2013)

(quoting United States ex rel. Hafter v. Spectrum Emergency Care, Inc., 

, 1160 (10th Cir. 1999)); see Kokkonen v. Guardian Life Ins. Co. of Am., 

, 377 (1994) (“It is to be presumed that a cause lies outside [federal

courts’] limited jurisdiction, and the burden of establishing the contrary rests

upon the party asserting jurisdiction.” (citation omitted)). Here, since NMOHVA

sought federal court review of the Forest Service’s action, it was incumbent on it

to demonstrate the elements of standing: (1) injury in fact, (2) causation, and (3)

redressability. As an organization, NMOHVA has standing to sue on behalf of its

members “when its members would otherwise have standing to sue in their own

right, the interests at stake are germane to the organization’s purpose, and neither

the claim asserted nor the relief requested requires the participation of individual

members in the lawsuit.” Friends of the Earth, Inc. v. Laidlaw Envtl. Servs.

(TOC), Inc., 

, 181 (2000).

                                          2

      To establish standing before the district court, NMOHVA submitted the

affidavit of Mark R. Werkmeister, a member of its board of directors. In this

brief affidavit, Mr. Werkmeister only stated that he “recreated on the Santa Fe

National Forest using [his] off-highway vehicle and . . . plan[ned] to return to the

National Forest . . . in the future.” Intervenors-Aplees.’ Suppl. App. at 7

(Standing Decl., filed Mar. 4, 2014). The district court correctly found that the


                                          12
cursory averments in this affidavit were insufficient to establish a concrete and

particularized injury that was either actual or imminent.

      Mr. Werkmeister’s affidavit is clearly deficient in two ways. First, “to

establish standing plaintiffs must show that they ‘use the area affected by the

challenged activity and not an area roughly in the vicinity of’” the activity.

(quoting Lujan v. Defs. of Wildlife, 

, 566

(1992)). Yet Mr. Werkmeister does not state that he has used, or intends to use,

any particular route affected by the designation process. See 

averments that an organization’s members “use[d] and enjoy[ed]” a forest without

identifying any “specific site[]” were insufficient). Given the immense size of the

forest (over 1.5 million acres), and the thousands of miles of routes available

under both the open-use regime and the selected Alternative 2M, it is possible

that Mr. Werkmeister’s “wanderings will bring him to a [route] . . . affected by

. . . the regulations,” 

it is patent that NMOHVA has not

demonstrated that this outcome is imminent. While Mr. Werkmeister did not need

to allege that he has “traversed each bit of land that will be affected by” the

designation process, he did at least have to show that he has “visited a particular

site” affected by the Forest Service’s actions. S. Utah Wilderness 

, 1156 (emphasis added); cf. 

(concluding that the affiant had

adequately demonstrated injury where he “specified areas which he has visited,




                                         13
averred that these specific areas will be affected . . . , and stated his interests will

be harmed by such activity”).

      Second, the affidavit only states a vague plan to visit the forest “in the

future.” Intervenors-Aplees.’ Suppl. App. at 7. But such “‘some day’

intentions—without any description of concrete plans, or indeed even any

specification of when the some day will be—do not support a finding of . . .

‘actual or imminent’ injury.” Defs. of 

; accord Colo.

Outfitters Ass’n v. Hickenlooper, --- F.3d ----, Nos. 14–1290, 14–1292, 

, at *9 (10th Cir. Mar. 22, 2016); see, e.g., 

(concluding that an affidavit fails to establish an imminent injury where “[i]t does

not assert[] . . . any firm intention to visit [an affected] location[]”); Tandy v. City

of Wichita, 

, 1284 (10th Cir. 2004) (stating that “a concrete, present

plan to use” the affected facilities was sufficient to state an injury in fact); cf.

WildEarth Guardians v. EPA, 

, 1206 (10th Cir. 2014) (concluding

that an affiant’s plans were sufficiently concrete where he “intend[ed]” to return

to the affected river “in June and July of this summer” (citation omitted)). Thus,

the district court correctly concluded that Mr. Werkmeister’s affidavit was

insufficient to establish standing.

      To be sure, in an attempt to rectify the failings of its original standing

affidavit, NMOHVA submitted a supplemental standing affidavit with its opening

appellate brief. This affidavit, however, was not presented to the district court;


                                            14
consequently, we will not consider it. United States v. Kennedy, 

,

1191 (10th Cir. 2000) (“This court will not consider material outside the record

before the district court.”). Standing must be present “at the outset of the

litigation” in the district court, Friends of the 

; see Mink v.

Suthers, 

, 1253–54 (10th Cir. 2007) (“But standing is determined at

the time the action is brought, and we generally look to when the complaint was

first filed, not to subsequent events.” (citation omitted)). And, if plaintiffs have

not been successful in demonstrating standing “at the time [the district court

enters] judgment,” they cannot “remedy the defect retroactively.” 

n.* (declining to consider post-judgment standing affidavits submitted

to the district court); see Swanson Grp. Mfg. LLC v. Jewell, 

, 240

(D.C. Cir. 2015) (“In determining whether the companies have standing, the court

may not consider on appeal supplemental declarations filed after entry of the

judgment appealed.”).

                                           3

      The district court ultimately found that NMOHVA had standing based on

“representations made during [a] hearing” regarding its submission of specific

routes for designation. Aplt.’s App. at 32. The court also determined that

“NMOHVA . . . presented in the administrative record a pattern of use sufficient

to meet the imminence requirement for standing.” 

But precisely what

representations the district court found persuasive, and which parts of the


                                          15
administrative record it believed established a “pattern of use,” 

is not

immediately apparent to us: the district court’s order does not provide any

specifics, and, importantly, NMOHVA has neither provided us a transcript of the

hearing before the district court, nor directed us to any document in the record

establishing a concrete and particularized injury.

                                           a

      As we have already indicated, since NMOHVA seeks to invoke our

jurisdiction, it “bears the burden of proof” on the issue of standing. Loving v.

Boren, 

, 772 (10th Cir. 1998). By providing us a lengthy

administrative record without any indication of where we might look to identify a

concrete injury to NMOHVA, it has not carried its burden; NMOHVA has, in

effect, asked us to shoulder its responsibility. Yet it is emphatically “not this

court’s duty to scour without guidance a voluminous record for evidence

supporting [a litigant’s] theory.” United States v. Lewis, 

, 1275

(10th Cir. 2010); see Eateries, Inc. v. J.R. Simplot Co., 

, 1232 (10th

Cir. 2003) (“We need not sift through the record to find [evidence to support a

party’s argument] . . . .” (alteration in original) (quoting Sil-Flo, Inc. v. SFHC,

      There are good institutional and practical reasons for our reluctance to

wade through reams of record documents without any guidance from the parties.

First, under our adversarial system of justice, we “rely on lawyers to identify the

pertinent facts and law.” In re Cont’l Cas. Co., 

, 295 (7th Cir. 1994);

see Niemi v. Lasshofer, 

, 1259 (10th Cir. 2013) (“In our adversarial

system we don’t usually go looking for trouble but rely instead on the parties to

identify the issues we must decide.”). We do not act as advocates for parties, and

we will not typically search out the facts necessary to support a litigant’s

position. See Ford v. West, 

, 777 (10th Cir. 2000) (“[W]e ‘are wary

of becoming advocates who comb the record . . . and make a party’s case for it.’”

(quoting Adler v. Wal-Mart Stores, Inc., 

, 672 (10th Cir. 1998)));

accord 

.

      Moreover, we have limited resources, and can ill afford to go on a treasure

hunt in the record without doing a disservice to other litigants. See DiCarlo v.

Keller Ladders, Inc., 

, 468 (8th Cir. 2000) (admonishing counsel for

“wasting th[e] Court’s limited resources” by submitting briefs without “even

              In fact, the Federal Rules of Appellate Procedure and this court’s

, 184

(1989) (per curiam) (“Every paper filed with the Clerk of this Court[] . . . requires

some portion of the institution’s limited resources.”). We are thus dismayed by

NMOHVA’s complete failure to provide us with any record citations to support

its standing. 5

                                          b

       At this juncture in the litigation, a conclusion that NMOHVA lacks

standing would certainly be regrettable. The able district court judge and the

parties have expended considerable resources addressing the merits of this

dispute. Therefore, notwithstanding NMOHVA’s dereliction, we have scoured

the extensive administrative record in this case, attempting to discern whether

NMOHVA has suffered a sufficiently concrete and particularized injury to

establish its standing. Despite devoting considerable time to this endeavor, we



       5
              We also echo the district court’s frustration that the Forest Service
was “not prepared and thus took no position on whether NMOHVA has standing
[to] bring this suit. While the [government] may have unlimited resources to
expend litigating a case . . . when there is potentially no subject matter
jurisdiction, the Court does not have such resources.” Aplt.’s App. at 33. Indeed,
given that the district court chastised the parties for their failure to adequately
address standing, and that the Intervenors raised standing in their appellate brief,
we are troubled that neither the Forest Service nor NMOHVA was better prepared
to address standing on appeal. At oral argument, counsel for the Forest Service
appeared to confuse the two affidavits submitted by NMOHVA—the one prior to
the district court’s judgment and the supplemental one that NMOHVA attached to
its appellate brief—while counsel for NMOHVA directed us to its reply brief,
which only references the supplemental affidavit that we have already rejected as
not properly part of the record we can consider.

                                          18
have come up short. We must conclude that NMOHVA’s standing has not been

demonstrated. If there is in fact a standing needle buried in the haystack of this

record, the blame for our failure to find it rests squarely at the feet of NMOHVA.

      Federal courts scrupulously guard the boundaries of their jurisdiction; they

are duty-bound not to permit a standing determination to rest on speculation or

conjecture. See, e.g., 

(stating that, in determining

standing, “speculation does not suffice”); Wyoming v. U.S. Dep’t of Interior, 

, 1233–34 (10th Cir. 2012) (“The petitioners have failed to meet their

burden of showing an injury in fact. Record facts consisting of conclusory

statements and speculative economic data are insufficient to lead us to any other

conclusion. Accordingly, we hold Petitioners lack standing to bring this civil

action.”); 

–84 (“A claimed injury that is contingent upon

speculation or conjecture is beyond the bounds of a federal court’s jurisdiction.”);

see also Nova Health Sys. v. Gandy, 

, 1157 (10th Cir. 2005) (“The

plaintiff’s burden of demonstrating causation is not satisfied when ‘[s]peculative

inferences are necessary to connect [its] injury to the challenged actions.’”

(alterations in original) (quoting Simon v. E. Ky. Welfare Rights Org., 

, 45–46 (1976))).

      In our laborious search, we did discover a piece of evidence that, at first

blush, offered some hope of providing a solid foundation for NMOHVA’s

standing, but ultimately we have concluded that it cannot bear the jurisdictional


                                         19
weight. Specifically, we focused on a brief passage in the EIS in which the

Forest Service explained why it chose not to analyze an alternative request

submitted by the “Blackfeather Trail Preservation Alliance [“Blackfeather”], a

subgroup of” NMOHVA. Aplt.’s App. at 132. NMOHVA could have standing

based on Blackfeather—a NMOHVA member that is itself an organization—if

Blackfeather’s members were injured as a result of the designation process. See

N.Y. State Club Ass’n, Inc. v. City of N.Y., 

, 9–10 (1988) (stating, in a

case involving a consortium of various clubs, that the consortium would have

standing if the “member associations would have standing to bring . . . suit on

behalf of their own individual members”).

      Blackfeather requested in this EIS passage “a large network of single-track

trails and tr[ai]ls riding areas, mainly in the Jemez Mountains.” Aplt.’s App. at

132. The Forest Service’s somewhat laconic response suggested that, although it

included some of Blackfeather’s requested trails in what ultimately became the

preferred alternative (i.e., 2M), it also designated many of them for alternatives

that were not selected, “especially in alternative 4.” 

This suggests the

possibility that Blackfeather was injured by the designation process because the

Forest Service apparently did not include some of its requested trails in the

preferred alternative.

      However, even if we could be confident—which is a hard state of mind to

achieve without any argument or other guidance from NMOHVA—that our


                                          20
interpretation of this brief passage is correct, see, e.g., FW/PBS, Inc. v. City of

Dall., 

, 231 (1990) (“[S]tanding . . . ‘must affirmatively appear in the

record.’” (emphasis added) (citation omitted)), the passage is problematic and

ultimately insufficient as proof of standing. It does not indicate with any

specificity which of Blackfeather’s requested trails may have been omitted from

the preferred alternative. And, even if this information could somehow be

gleaned from the record, there is a more fundamental problem, which is

dispositive: the passage offers no indication of whether Blackfeather’s members

regularly use, and have concrete plans to return to, the requested trails.

      This evidentiary deficiency as to the use and planned use of the affected

area, viewed alone, renders the EIS passage insufficient to establish NMOHVA’s

standing through Blackfeather, just as this type of defect doomed NMOHVA’s

attempt to establish standing in the district court through the averments of Mr.

Werkmeister’s affidavit. See, e.g., 

(concluding that an

affidavit fails to establish an imminent injury where “[i]t does not assert[] . . . any

firm intention to visit [an affected] location[]”); Colo. Outfitters Ass’n, 

, at *7 (in holding that plaintiffs had not established standing,

commenting that “we see no evidence indicating they had even a general intent to

engage in conduct that might violate [the state statute at issue], let alone any

specific plans to do so”); 

(stating that “a concrete,

present plan to use” the affected facilities was sufficient to state an injury in


                                           21
fact); see also Friends of the 

(“We have held that

environmental plaintiffs adequately allege injury in fact when they aver that they

use the affected area and are persons ‘for whom the . . . recreational values of the

area will be lessened’ by the challenged activity.” (quoting Sierra Club v. Morton,

, 735 (1972))). In other words, this evidence does not demonstrate

that Blackfeather’s members have “a ‘direct stake in the outcome’” of the present

dispute, S. Utah Wilderness 

(quoting Comm. to Save the

Rio Hondo v. Lucero, 

, 451 (10th Cir. 1996)). And, therefore,

NMOHVA cannot establish standing through Blackfeather. Thus, in our view,

what is perhaps the most promising piece of evidence that we unearthed in the

record for establishing NMOHVA’s requisite injury is insufficient; it will not take

NMOHVA across the jurisdictional finish line. 6

      6
             The EIS passage containing Blackfeather’s site request was one of a
few documents meriting further study—all of them proved insufficient to
establish standing. Our review underscores why courts are loath to play
detective, hunting down clues in the nooks and crannies of the administrative
record. At best, those documents worthy of further study were plagued by similar
problems as the Blackfeather EIS passage. For example, in a document titled
“Report on Site Specific Suggestions,” which summarizes comments received by
the Forest Service regarding the designation of various trails, Mr. Werkmeister
unsuccessfully requested that the “routes in the Cuba District like the Smokey
Bear Hill loops” be designated for motorized use. Aplee.’s Suppl. App. at 246
(Report on Site Specific Suggestions). He noted that NMOHVA members are
“frequent visitors to the area in [their] vehicles and hope to continue this
important tradition for many years to come.” 

Service excluded
this area from the alternatives, noting that Mr. Werkmeister’s “suggestion is
vague, [and that] also concerns with wildlife issues exist in this area.” 

Werkmeister’s comment does endeavor to identify (albeit vaguely) particular
                                                                        (continued...)

      In sum, we are constrained to conclude that NMOHVA lacked standing and,

consequently, the district court did not have subject-matter jurisdiction to rule on

the merits of this case. Our precedent charts the path forward. We are

constrained to dismiss this appeal and remand the case to the district court with

instructions to vacate its judgment and dismiss NMOHVA’s lawsuit without

prejudice. See, e.g., Bronson v. Swensen, 

, 1102 (10th Cir. 2007)

(“[W]e hold that plaintiffs lack standing to bring claims against Swensen based

upon the purported unconstitutionality of Utah’s criminal prohibition of

polygamy. We therefore VACATE the district court’s judgment in favor of

Swensen on the merits of these criminal-prohibition claims and REMAND the

case for entry of an order dismissing these claims for lack of subject matter

jurisdiction.”); Estate of
