Clue Emerges in Search for Missing 73 Year Old Hiker in Mesa Verde National Park

MESA VERDE NATIONAL PARK, COLORADO In a recent development in the ongoing search for 73-year-old Thomas Irwin, who disappeared while hiking in Mesa Verde National Park, authorities have discovered a potential new clue that could provide insight into his whereabouts.

Irwin, described as a 6-foot-tall white male weighing 250 pounds with gray hair and brown eyes, was last seen on January 15, 2024, hiking the Petroglyph Point Trail. Wearing a dark gray flannel shirt, blue jeans, and tan hiking boots, Irwin, who suffers from cognitive impairment and requires medication, has become the focus of an extensive search effort by park rangers and local authorities.

The Colorado Bureau of Investigation has reported that Irwin’s vehicle was found in the park, but there had been no sign of him until the recent development. A cellphone, believed to belong to Irwin, was turned into the park’s museum on January 16. Authorities are now seeking more information from the individual who found the phone, as well as from anyone who was in the park on January 15.

The Petroglyph Point Trail, described as a 2.4-mile, strenuous loop, is known for its challenging terrain, including narrow, rugged paths and steep drop-offs. The trail leads to a significant petroglyph panel, an area of historical and archaeological importance.

Park officials have issued a reminder about the dangers of hiking in the park, emphasizing the risks of dehydration, altitude sickness, and the treacherous cliff edges along the trails. Hikers are advised to drink water, rest frequently, and stay clear of unstable cliff edges.

The National Park Service is urging anyone with information about Irwin’s whereabouts or who may have seen him on January 15 to contact Mesa Verde Dispatch at (970)529-4461 or the Colorado Bureau of Investigation at 970-565-8441.
