MESA, Colo. (KKCO/KJCT) -- UPDATE: The Delta County Sheriff's Office confirmed Tuesday morning the bodies of two men were recovered from the lake.
The Delta County Coroner will be responsible for identifying them.
Two men are presumed dead after law enforcement believes they took a Sno-Cat on a frozen lake near Grand Mesa Lodge and fell through the ice.
"I could believe a snowmobile, those guys are always out on the lakes," Jeff Shimer, an outdoorsman in the area, said. "I don't know why they would be driving a Sno-Cat out on the lake."
Monday, search and rescue teams out of Summit County were using an underwater drone to confirm that suspicion.
According to the Delta County Sheriff's Office, four people, all from the Western Slope, checked into a room at the Grand Mesa Lodge Saturday afternoon.
At around 1:00 Sunday morning the owner of that lodge says he believes he heard a Sno-Cat start.
Later that morning the lodge grew concerned after several folks didn't check out of their room when expected, that's when the Sheriff's Office was called.
Two of those four people had left the lodge and were safe, two still unaccounted for. One of the men has been identified as 30-year-old Ryan Wells. The other hasn't been identified yet.
A family member of one of the missing men showed up with a snowmobile and found tracks going out on the ice, and then, a hole about the size of the Sno-Cat.
The search and rescue team showed up Sunday to search the lake for any clues that the men had escaped, and found none.
"That's kind of crazy," Shimer said. "The back country is fun, you just gotta be safe."
