The National Park Service acknowledges that missing persons cases occur within park boundaries but maintains these incidents are consistent with statistical expectations given the 312 million annual recreational visits to federal parklands. Individual cases are entered into the National Law Enforcement Telecommunications System (NLETS) and managed by appropriate jurisdictional authorities. Skeptical analysis by researcher Kyle Polich, published in Skeptical Inquirer (2017), concluded that after examining Paulides' data, "not a single case stands out nor do the frequencies involved seem outside of expectations." The NPS notes the absence of a centralized missing persons database reflects distributed case management across federal, state, and county jurisdictions rather than deliberate omission.
Missing 411: The National Park Vanishings
Case Summary
Since 2012, former police detective David Paulides has documented over 1,700 unexplained disappearances in North American wilderness areas. Victims vanish without trace, often within sight of companions, leaving behind patterns that defy conventional explanation—and a National Park Service that claims it keeps no centralized record of the missing.

6 itemsStacy Arras Camera Lens Cap
The only physical evidence ever recovered from the disappearance of 14-year-old Stacy Ann Arras, who vanished from Yosemite's Sunrise High Sierra Camp on July 17, 1981. Found along the trail toward Sunrise Lakes—the direction witnesses watched her walk before she disappeared behind trees and was never seen again. Despite a 9-day formal search involving 150 searchers, helicopters with infrared radar, and tracking dogs covering a 3-5 square mile area, no other trace of Stacy, her camera, clothing, or belongings was ever found.

4 reportsInvestigation Verdict
The individual cases are undeniably real and heartbreaking—the FBI file on Dennis Martin is public, the NPS admits Stacy Arras is still missing, and Carl Higdon's medical records document his disoriented state when found. But is something genuinely anomalous happening, or has Paulides catalogued the tragic but expected outcomes of millions entering dangerous wilderness? The "profile points" feel compelling—until you realize storms are common in mountains, dogs lose scent in rain, and no search grid is perfect. Yet the NPS's refusal to maintain basic records feels genuinely suspicious. Whether that's bureaucratic incompetence protecting tourism revenue, or something darker, remains the real mystery.
