DENVER (AP) — Authorities say only one of two missing Colorado snowmobile riders was found alive after the men were stranded inside a remote area of Utah’s Dinosaur National Monument. The Denver Post reported the 65-year-old who was rescued and the 58-year-old who did not survive were located Saturday. The National Park Service says the men were reported missing Thursday and believed to have been snowmobiling near the northwest boundary of the monument near the Utah and Colorado border. The Uintah County Sheriff’s Office says the men were inexperienced riders who were previously rescued from the same area Feb. 29.
