ROCKY MOUNTAIN NATIONAL PARK — Members of Rocky Mountain National Park Search and Rescue found a man’s body on a steep and rugged section of Longs Peak Friday morning, and they believe it is a hiker who was reported missing in the area earlier this week.

Jens “Jay” Yambert, 60, is from Urbana, Illinois. He is believed to have started his attempt to summit the mountain from the Longs Peak Trailhead at 2 p.m. Sunday, and was reported overdue by a family member on Tuesday.

His rental car was found at the trailhead that same day, and it was the beginning of a multi-day search for the man on the 14,259’ peak in Rocky Mountain National Park.

Hikers told search and rescue that they say Yambert on Monday on the popular Keyhole route. Weather was poor that day, with sleet, rain and wind.

The body believed to be Yambert’s was found west of Keplinger’s Couloir at 12,600 feet. It’s unknown when recovery efforts will take place because of the remote location and severe weather in the area on Friday afternoon.

Rangers will stay nearby on Friday night and begin an investigation on Saturday, according to a news release from Rocky Mountain National Park.
