Encounteringbears is a concern in the Wind River Range.[5] There are other concerns as well, includingbugs,wildfires,adverse snow conditions andnighttime cold temperatures.[6]
Importantly, there have been notable incidents, includingaccidental deaths, due tofalls from steep cliffs (amisstep could be fatal in thisclass 4/5 terrain) and due tofalling rocks, over the years, including 1993,[7] 2007 (involving an experiencedNOLS leader),[8] 2015[9] and 2018.[10] Other incidents include a seriously injured backpacker being airlifted nearSquareTop Mountain[11] in 2005,[12] and a fatal hiker incident (from an apparentaccidental fall) in 2006 that involved statesearch and rescue.[13] TheU.S. Forest Service does not offer updated aggregated records on the official number of fatalities in the Wind River Range.
