A sample:
On a search-and-rescue in 2000, two rangers were riding in a Blackhawk helicopter when it crashed into the west side of the mountain, tumbling over the steep slope before coming to a halt. Four crew members, a Fox 40 cameraman, and rangers Dan Towner and Matt Hill were able to emerge from the wreckage unhurt. Towner and Hill managed to get the five men down from 11,000 to 9,000 feet, where another Blackhawk landed to take them to safety. After getting the others on board, the two rangers decided they'd rather ski back down to Bunny Flat.
"We figured, rather than taking another helicopter ride that day, we'd take our chances with unstable snow," Towner remembered.
