LILLEHAUG, Justice.
A 4-year-old boy, Shungmanitou Washtay Kihega ("Shawn"), wandered off during a family party on respondent Peter Carlson's property. Shawn's relatives found him face down in the Mississippi River. Shawn was revived, but he suffered severe brain damage from the near-drowning. Appellant Amanda Senogles, as parent and guardian of Shawn, filed this lawsuit against Carlson, alleging that, as the landowner, he violated his duty of care to his invitee, Shawn. The district court granted Carlson's motion for summary judgment and the court of appeals affirmed. Because summary judgment should have been denied, we reverse and remand.
On August 23, 2013, Senogles left her children, Shawn (4 years old), and Bear (3 years old), with her mother L.L. for the weekend. The next day, L.L. took the children to a family party held outdoors at Carlson's house in celebration of a relative's birthday. Carlson was Shawn's and Bear's great-uncle. Carlson's property featured about 76 feet of rocky shoreline on the Mississippi River.
It was a hot summer day. At the time of the party, the temperature was approximately 90 degrees. After arriving at the party, Shawn and several other children wanted to go swimming in the river. Shawn first asked his great-aunt, K.A., to take him swimming, but K.A. was busy "set[ting] up" for the party. Shawn waited on the steps with L.L. for 5 to 10 minutes until his great-uncle Paul Carlson agreed to take Shawn swimming.
After about 20 minutes, everybody (including Shawn) left the river because it was time to eat. K.A. told the children that swimming was over, at least for now. The swimming party dispersed. Shawn remained in his swimwear. Some children played yard games and others, including Shawn, played basketball.
About 10 minutes after the children left the water, the family realized that Shawn was missing. The family began searching for Shawn and within 3 minutes found him lying face down in the river. Family members were able to resuscitate Shawn, but he suffered severe brain damage.
Senogles, as Shawn's parent and guardian, sued Carlson, alleging that Carlson breached his duty of care as a landowner to his invited guest, because he failed to prevent Shawn's access to the river, failed to supervise Shawn, failed to have a safety plan for the child guests, and failed to warn Shawn of the foreseeable dangers on the property.
On the motion for summary judgment, most of the facts were undisputed with the exception of Shawn's prior swimming experience. Senogles acknowledged that Shawn swam once at a pool and another time at a water park, but asserted that he "had no experience around lakes or rivers" before the day in question. Carlson asserted that Shawn had "experience around lakes and rivers before the party."
The district court granted Carlson's motion for summary judgment on the ground that the harm to Shawn was not foreseeable to Carlson. The court of appeals affirmed the grant of summary judgment on a different ground: that Carlson was not liable because the danger was "obvious" to Shawn. The court of appeals did not reach the issue of the foreseeability of the danger.
This case involves an appeal from an order granting summary judgment in favor of the landowner on a claim of negligence.
We view the evidence in the light most favorable to the party against whom summary judgment was granted. Lubbers v. Anderson, 539 N.W.2d 398, 401 (Minn. 1995). Any doubt regarding the existence of a material fact is resolved in favor of that party. Rathbun v. W.T. Grant Co., 300 Minn. 223, 219 N.W.2d 641, 646 (1974); see also Rochester City Lines, Co. v. City of Rochester, 868 N.W.2d 655, 661 (Minn. 2015) (holding that the evidence is viewed "in the light most favorable to the nonmoving party" and all doubts are resolved against the moving party). Similarly, "all factual inferences must be drawn against the movant for summary judgment." Sauter v. Sauter, 244 Minn. 482, 70 N.W.2d 351, 353 (1955). We must not "weigh facts." Stringer v. Minn. Vikings Football Club, LLC, 705 N.W.2d 746, 754 (Minn. 2005). Summary judgment is a "blunt instrument" that should not be granted "when reasonable persons might draw different conclusions from the evidence presented." Osborne v. Twin Town Bowl, Inc., 749 N.W.2d 367, 371 (Minn. 2008) (citation omitted).
A district court may grant summary judgment in favor of a defendant in a negligence action "when the record reflects a complete lack of proof" on any one of these four elements: (1) the existence of a duty of care, (2) a breach of that duty, (3) an injury, and (4) the breach of duty being the proximate cause of the injury. Louis, 636 N.W.2d at 318 (citing Lubbers, 539 N.W.2d at 401). In this case, the district court granted summary judgment in favor of Carlson on the first element, the existence of a duty of care.
Our law regarding a landowner's duty of care is well-established. A "landowner generally has a continuing duty to use reasonable care for the safety of all entrants." Id. at 319 (citing Baber v. Dill, 531 N.W.2d 493, 496 (Minn. 1995)). "Entrants" refers to both invitees and licensees. See Louis, 636 N.W.2d at 318-19; Peterson v. Balach, 294 Minn. 161, 199 N.W.2d 639, 647 (1972). In this case, the parties agree that Shawn, an invited guest, was an entrant. Thus, Carlson generally had a continuing duty to use reasonable care for Shawn's safety.
But the landowner's duty of care to entrants regarding a particular danger on the property is not unlimited. Restatement (Second) of Torts § 343A (Am. Law Inst. 1965), which we have adopted, carves out an exception to the duty, and then carves out an exception to the exception. A landowner is not liable to invitees when the "danger is known or obvious to them, unless the possessor should anticipate the harm despite such knowledge or obviousness." Peterson v. W.T. Rawleigh Co., 274 Minn. 495, 144 N.W.2d 555, 557-58 (1966) (citation omitted) (internal quotation marks omitted) (adopting and applying section 343A).
Whether Carlson should have anticipated the harm is an issue of foreseeability. Whether a risk was foreseeable depends on "whether the specific danger was objectively reasonable to expect, not simply whether it was within the realm of any conceivable possibility." Whiteford ex rel. Whiteford v. Yamaha Motor Corp., 582 N.W.2d 916, 918 (Minn. 1998). The foreseeability of danger "depends heavily on the facts and circumstances of each case." Doe 169 v. Brandon, 845 N.W.2d 174, 179 (Minn. 2014). As we reaffirmed recently, when the issue of foreseeability is clear, the court, as a matter of law, should decide it, but in close cases, the issue of foreseeability is for the jury. Montemayor v. Sebright Prods., Inc., 898 N.W.2d 623, 629 (Minn. 2017); see also Domagala v. Rolland, 805 N.W.2d 14, 27, 27 n.3 (Minn. 2011); Bjerke v. Johnson, 742 N.W.2d 660, 667-68 (Minn. 2007) (citing Whiteford, 582 N.W.2d at 918); Lundgren v. Fultz, 354 N.W.2d 25, 28 (Minn. 1984); Ill. Farmers Ins. Co. v. Tapemark Co., 273 N.W.2d 630, 636-38 (Minn. 1978) (holding that the issue of foreseeability should be submitted to the jury where "reasonable persons might differ"). As Montemayor emphasized, the issue of foreseeability is "close" and must go to the jury when the "evidence presents an explicit dispute of material fact" or when a reasonable person "might draw different conclusions from the evidence." 898 N.W.2d at 629 n.3.
The threshold question in this case is whether Carlson has shown that he is not liable because the danger of the activity or condition on the land was "known or obvious" to Shawn. See Louis, 636 N.W.2d at 322 (remanding to the district court for consideration of whether the harm to the plaintiff "was either known to him or one that he reasonably should have been expected to know"); Ill. Farmers, 273
"Known" is a subjective test that depends upon the entrant's actual "appreciation of the danger." Restatement (Second) of Torts § 343A cmt. b (Am. Law Inst. 1965). "Thus the condition or activity must not only be known to exist, but it must also be recognized that it is dangerous, and the probability and gravity of the threatened harm must be appreciated." Id.
We may proceed quickly past the "known" test. Carlson did not move for summary judgment on that theory. The district court made no finding on whether Shawn actually knew of the danger of returning to the river to swim alone. And the court of appeals' holding was based solely on the "obvious" test, to which we now turn.
Whether a danger is "obvious" is an objective test. Munoz v. Applebaum's Food Mkt., Inc., 293 Minn. 433, 196 N.W.2d 921, 922 (1972). The danger is "obvious" only if "both the condition and the risk are apparent to and would be recognized by a reasonable [person] `in the position of the visitor.'" Louis, 636 N.W.2d at 321 (quoting Restatement (Second) of Torts § 343A cmt. b)).
It is black-letter law that a child's past experience informs an objective test, such as the obviousness of a risk. The objective standard for children is set forth in the Restatement (Second) of Torts § 283A cmt. b:
We recognized the same nearly 70 years ago. Audette v. Lindahl, 231 Minn. 239, 42 N.W.2d 717, 719 (1950) (stating that a child is required to exercise the "degree of care which would ordinarily be exercised by a child of that age, experience, and intelligence, under the same or similar circumstances"); see also Peterson v. Minn. Power & Light Co., 206 Minn. 268, 288 N.W. 588, 589 (1939) (considering the decedent's "age and background" when applying the objective standard of a reasonable person). Similarly, in Toetschinger v. Ihnot, 312 Minn. 59, 250 N.W.2d 204, 210 (1977), we cautioned that, "when the case is submitted to the jury, it is to be made clear ... that the degree of care expected of a child is that commensurate with the age, mental capacity, and understanding of children of similar age acting under similar circumstances." We added, "[t]his is a matter which jurors chosen from the community generally are particularly well able to assess." Id.
Further, there were disputed material facts sufficient to raise a genuine issue regarding whether Shawn "should have known" of the danger posed by swimming unsupervised. Specifically, the parties disputed Shawn's prior swimming experience. Shawn's disputed experience swimming in rivers was material to the question of whether a reasonable child in his position would consider the danger of swimming in the river to be obvious.
The district court's analysis on obviousness (embedded in its foreseeability analysis) seems to have been influenced by a statement from a legal encyclopedia that the "danger embodied by water may reasonably be expected, under ordinary conditions, to be fully understood and appreciated by any child of an age to be allowed at large. The courts have frequently observed in this connection that even young children have a natural fear of water." 62 Am. Jur. 2d Premises Liability § 370 (2d ed. 2005) (citations omitted).
By contrast, our case law contains scenarios in which people — both adults and children — failed to appreciate the dangers of water and a negligence claim was submitted to the jury. See, e.g., Louis, 636
We have also recognized that dangers that are obvious to adults may not be fully appreciated by children of Shawn's age. See Heitman v. Lake City, 225 Minn. 117, 30 N.W.2d 18, 23 (1947) (stating, "[c]hildren, through childish inattention, may fail to observe conditions which an adult might reasonably be expected to discover," in a case involving a 7-year-old child who drowned); see also Gryc v. Dayton-Hudson Corp., 297 N.W.2d 727, 743 (Minn. 1980) (stating that a 4-year-old child was "incapable of appreciating the risk" that her pajamas could ignite from an electric burner); Doren v. Nw. Baptist Hosp. Ass'n, 240 Minn. 181, 60 N.W.2d 361, 367 (1953) (stating that a 6-year-old child "would not be likely to ... realize the risk" of playing near a pile of ash); Decker v. Itasca Paper Co., 111 Minn. 439, 127 N.W. 183, 184 (Minn. 1910) (stating that the danger of playing in an elevator was not obvious to a 5-year-old child).
Further, we have specifically adopted Restatement (Second) of Torts § 339 (Am. Law. Inst. 1965), regarding child trespassers attracted to nuisances. Szyplinski v. Midwest Mobile Home Supply Co., 308 Minn. 152, 241 N.W.2d 306, 309-10 (1976) (adopting section 339 of the Restatement). Comment j of section 339 notes that a landowner's duty under the attractive-nuisance doctrine is extended to instances in which "the possessor knows that children too young to appreciate such dangers are likely to trespass on his land."
The dissent cites a number of cases from foreign jurisdictions to the effect that water is an obvious danger to all children. These cases are not consistent with our own precedent, which has rejected blanket rules. Further, other courts across the country have reached the opposite conclusion. See, e.g., King v. Lennen, 53 Cal.2d 340, 1 Cal.Rptr. 665, 348 P.2d 98, 99-100 (1959) (emphasizing that "the circumstance that a condition giving rise to injury is common in character does not necessarily exclude liability, that the ability to appreciate danger varies with the age and mental capacity of the child," and holding that the 1-and-a-half-year-old child "could not reasonably be expected to realize or appreciate the danger" of a swimming pool);
We decline to adopt a categorical rule that the danger of swimming unattended in any Minnesota river, lake, or pool is necessarily obvious to all children, no matter how young and inexperienced. In this case, in which there are disputed facts regarding Shawn's experience and differing reasonable inferences about whether the danger of returning to the river should have been obvious to Shawn, Carlson did not carry his burden to establish the exception to his duty as a landowner. Summary judgment should not have been granted.
But even assuming that the danger had been obvious to Shawn, Carlson would still owe a duty to Shawn if Carlson should have anticipated the harm. A landowner is not relieved of the duty to invitees for dangers that are known or obvious if the landowner "should anticipate the harm despite such knowledge or obviousness." Restatement (Second) of Torts § 343A. In this regard, the court of appeals erred when it ended its analysis once it concluded that "the danger of the river was open and obvious to Shawn. We therefore need not determine whether it was foreseeable that Shawn would re-enter the river." Senogles, 2016 WL 3659314, at *3. Instead, the court of appeals should have determined whether the exception to obviousness — foreseeability — applied. That is where we pick up the analysis.
"When determining whether a danger is foreseeable, we `look at whether the specific danger was objectively reasonable to expect, not simply whether it was within the realm of any conceivable possibility.'" Foss v. Kincade, 766 N.W.2d 317, 322 (Minn. 2009) (quoting Whiteford, 582 N.W.2d at 918). What is objectively reasonable for the landowner to expect depends, in part, on the age of the entrant. We have previously recognized that children often behave in dangerous ways and that adults should anticipate that they will do so. See Slinker v. Wallner, 258 Minn. 243, 103 N.W.2d 377, 382 (1960) ("[T]here is virtually no condition upon any land with which a child may not possibly get himself into trouble.... Children may, and do, do practically everything." (citation omitted) (internal quotation marks omitted)); Mattson v. Minn. & N.W.R. Co., 95 Minn. 477, 104 N.W. 443, 446 (1905) ("Children, wherever they go, must be expected to act upon childish instincts and impulses; and others, who are chargeable with a duty of care and caution towards them, must calculate upon this, and take precautions accordingly.").
Finally, Carlson asks that we announce a new rule of law that a Minnesota landowner owes no duty of care to a child entrant if the child enters the land accompanied by a parent or guardian, no matter how foreseeable the harm. We decline Carlson's request. No Minnesota precedent supports such a blanket rule, and it would undermine not only our foreseeability jurisprudence, but also our system of comparative fault. See Minn. Stat. § 604.01, subd. 1 (2016) (stating that the court may "direct the jury to find separate special verdicts determining ... the percentage of fault attributable to each party"). Our state has rejected or significantly limited other such absolute tort doctrines that increase "the likelihood of unfairness" and has opted for a comparative fault framework that "contemplates justice for all parties." Toetschinger, 250 N.W.2d at 208, 210. See Minn. Stat. § 604.01, subd. 1 ("Contributory fault does not bar recovery... if the contributory fault was not greater than the fault of the person against whom recovery is sought"); Olson v. Hansen, 299 Minn. 39, 216 N.W.2d 124, 127-28 (1974) (discussing the limits of the assumption-of-risk doctrine); Koval v. Thompson, 272 Minn. 53, 136 N.W.2d 789, 792 (1965) (discussing the limits of the last-clear-chance and discovered-peril doctrines).
Although we do not adopt the absolute no-duty rule that Carlson proposes, nothing in our decision today prevents Carlson from arguing to the jury that, because he understood that Shawn was to be supervised by others, Carlson could not foresee the danger to Shawn, Carlson was not negligent, or Carlson's actions were not the proximate cause of Shawn's injury. We decide only that Senogles is entitled to a trial.
For the foregoing reasons, we reverse the decision of the court of appeals and remand to the district court for further proceedings consistent with this opinion.
Reversed and remanded.

ANDERSON, Justice (dissenting).
This case involves an almost 5-year-old child who nearly drowned in a tragic accident. But not all tragic accidents are compensable in litigation. Here, the court unearths a factual dispute where none exist to conclude that a jury could find that the landowner should have anticipated this injury and, therefore, the landowner had a duty to protect the child from the Mississippi River. By so holding, the court opens the door to a significant, and unwarranted, expansion of social host liability.
It is unnecessary for a jury to decide this case because the material facts are undisputed. The Mississippi River is an obvious danger and there was no reason to anticipate the injury despite this obviousness. Therefore, I respectfully dissent.
Summary judgment is appropriate when there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. Osborne v. Twin Town Bowl, Inc., 749 N.W.2d 367, 371 (Minn. 2008). The genuine issue of material fact must be shown by substantial evidence. Gunderson v. Harrington, 632 N.W.2d 695, 704 (Minn. 2001). A metaphysical doubt as to a factual issue will not defeat a motion for summary judgment. DLH, Inc. v. Russ, 566 N.W.2d 60, 71 (Minn. 1997). A factual dispute is "material" when its resolution will affect the out-come of the case. Antonello v. Comm'r of Revenue, 884 N.W.2d 640, 645 (Minn. 2016).
In a negligence action, summary judgment is to be granted when there is a complete lack of proof on any of the four elements of a negligence claim: (1) the existence of a duty of care, (2) a breach of that duty, (3) an injury, (4) or proximate causation. Gradjelick v. Hance, 646 N.W.2d 225, 234 (Minn. 2002). Here, Carlson argues that Senogles has not proven the existence of a duty of care.
We have adopted the Restatement (Second) of Torts § 343A (Am. Law Inst. 1965), which states that a landowner does not owe a duty to his visitors "for physical harm caused to them by any activity or condition on the land whose danger is known or obvious to them, unless the possessor should anticipate the harm despite such knowledge or obviousness."
A danger is obvious when "both the condition and the risk are apparent to and would be recognized by a reasonable man, in the position of the visitor, exercising ordinary perception, intelligence, and judgment."
We have repeatedly stated that the existence of a legal duty is a question of law to be determined by the court.
Nevertheless, the court holds that a jury must decide whether the danger of the Mississippi River was objectively obvious because it concludes that one fact — Shawn's experience with water — is disputed. Senogles did not argue before the district court that Shawn's experience with water was a genuine issue of material fact.
Because there are no genuine issues of material fact, we must decide, based on the undisputed facts, whether the danger of the river was obvious to a reasonable person in Shawn's position. See id. Applying this test in other cases, we have concluded that water is an obvious danger. For example, in Hammerlind v. Clear Lake Star Factory Skydiver's Club, a skydiver was blown off course, missed the approved skydiving drop zone, landed in a lake, and drowned. 258 N.W.2d 590, 593 (Minn. 1977). We held that the owner of the land where the drop zone was located did not owe a duty to the skydiver because the lake "posed an obvious danger to parachutists, given its proximity to the drop zone and the danger of water generally to jumpers." Id. at 594. We also held that the landowner had no reason to anticipate the injury despite the obviousness of the danger. Id.
Similarly, other courts have found that lakes and rivers pose obvious dangers. For example, numerous courts have concluded that the danger of jumping into a river is obvious. See Harmon v. United States, 532 F.2d 669, 671 (9th Cir. 1975) (concluding that the danger of drowning in a river was obvious to white-water rafters); Suchy v. City of Geneva, 380 Ill.Dec. 395, 8 N.E.3d 565, 573 (Ill. App. Ct. 2014) ("[B]odies of water are deemed to present open and obvious dangers, whether they are natural or man-made.... [A body of] water's dangers are considered to be apparent to both experienced swimmers and young children."); Greenslade v. Mohawk Park, Inc., 59 Mass.App.Ct. 850, 798 N.E.2d 336, 339 n.4 (2003) (citing cases).
Nevertheless, the court concludes that the danger might not have been obvious to Shawn because, at the time of his injury, he was 4 years and 8 months old. But this conclusion is against the weight of our case law. We have recognized that even young children can appreciate danger. For example, in a case involving a child less than 6 years old, we stated that children under the age of 7 have some "capacity ... to appreciate and avoid the risks of vehicular traffic." Toetschinger v. Ihnot, 312 Minn. 59, 250 N.W.2d 204, 211 (1977). In a case involving a 7-year-old child who drowned, we noted that "it is generally conceded that the ordinary body of water, even though it be artificial, while it does involve the risk of death or serious harm, does not constitute an unreasonable risk thereof because even a child to some extent appreciates the risks that are connected with it." Johnson v. Washington Cty., 518 N.W.2d 594, 600 (Minn. 1994) (citation omitted).
In Davies v. Land O'Lakes Racing Ass'n, a 5-year-old child drowned after falling into a drainage catch basin that had filled with water on a racetrack construction site. 244 Minn. 248, 69 N.W.2d 642, 643 (1955). Although we held the landowner liable, we painstakingly emphasized the unique dangers of the particular water at issue and distinguished it from other bodies of water. As the court points out, we
In summary, looking solely at our case law going back many decades, I find little precedent supporting the court's analysis. More critically, by concluding that the obviousness of the danger of the Mississippi River is a fact question for the jury, the court departs from our case law. The result likely will be an enormous expansion in social host liability.
But it is not only Minnesota case law that the court ignores on its way to a jury trial in this case. Other courts also have concluded that water is an obvious danger to children. See, e.g., Long v. Manzo, 452 Pa.Super. 451, 682 A.2d 370, 375 (1996) ("Generally, because ponds, pools, lakes, streams and other waters embody perils that are deemed to be obvious to children of the tenderest years, no liability attaches to a possessor of a pond."); Cooper v. Diesel Serv., Inc., 254 Ark. 743, 496 S.W.2d 383, 385 (1973) (stating in a case involving a 6-year-old that "the danger inherent in water in a pond is or should be obvious to a child"), overruled on other grounds by Farm Bureau Mut. Ins. Co. of Ark. v. Henley, 275 Ark. 122, 628 S.W.2d 301 (1982); McGill v. City of Laurel, 252 Miss. 740, 173 So.2d 892, 898 (Miss. 1965) (explaining that a 6-year-old could understand the danger of drowning); Hanners v. City of Ashland, 331 S.W.2d 729, 730 (Ky. 1959) (stating in a case involving an 8-year-old that "the possible hazard of use [of bodies of water] is generally appreciated even by children of tender years"); Mellas v. Lowdermilk, 58 N.M. 363, 271 P.2d 399, 401 (1954) ("Ponds, pools, lakes, streams, and other waters embody perils that are deemed to be obvious to children of the tenderest years."); Dennis v. Spillers, 199 Okla. 311, 185 P.2d 465, 466 (1947) (stating in a case involving a 7-year-old that "[a] body of water — either standing, as in ponds and lakes, or running, as in rivers and creeks, or being and flowing, as on the shores of seas and bays — is a natural object incident to all countries which are not deserts. Such a body of water may be found in or close to nearly every city or town in the land; the danger of drowning in it is an apparent open danger, the knowledge of which is common
Given the voluminous case law recognizing the obviousness of the danger of water, the risk of the Mississippi River was obvious to an objectively reasonable child of 4 years and 8 months.
Having concluded that the Mississippi River is an obvious danger, it is necessary to decide whether Carlson should have anticipated the injury despite the obviousness of the danger. See Baber, 531 N.W.2d at 496. In deciding that an injury should not be anticipated despite the obviousness of the danger, we have recognized that, especially when dealing with young children, "the realm of possible harm is much larger than the realm of reasonably foreseeable harm." Foss, 766 N.W.2d at 323. When other adults are present, we have considered whether the landowner knew that visiting children "frequently wandered away" from their guardians in the particular location where the injury occurred. Peterson v. Richfield Plaza, Inc., 252 Minn. 215, 89 N.W.2d 712, 718 (1958); see also Hammerlind, 258 N.W.2d at 593 (concluding that the pilot of a skydiving plane owed no duty to an injured skydiver because "a reasonable pilot could rely on the jump master" to check the skydiver's safety equipment).
Here, even if it could be anticipated that Shawn would attempt to return to the river unsupervised, it is not reasonable to anticipate that he would succeed in walking to the river unnoticed.
Because I conclude that the Mississippi River poses an obvious danger and that Carlson should not have anticipated Shawn's injury despite this obviousness, I would hold that Carlson did not owe a duty

Plainly, Senogles considered the fact of Shawn's inexperience with lakes and rivers to be material. Although she did not list it in her section of "material facts in dispute," Carlson considered the fact to be material and directly disputed it on page 2 of his reply brief. Therefore, on Carlson's motion for summary judgment, the parties disputed a material fact: Shawn's experience with lakes and rivers.
The parties litigated the case under section 343A, which we have expressly adopted. We use that section's framework for this analysis.
