Hazards

Main articles: Hazards of outdoor recreation and Mountaineering § Hazards

Encountering bears is a concern in the Wind River Range.[5] There are other concerns as well, including bugs, wildfires, adverse snow conditions and nighttime cold temperatures.[6]

Importantly, there have been notable incidents, including accidental deaths, due to falls from steep cliffs (a misstep could be fatal in this class 4/5 terrain) and due to falling rocks, over the years, including 1993,[7] 2007 (involving an experienced NOLS leader),[8] 2015[9] and 2018.[10] Other incidents include a seriously injured backpacker being airlifted near SquareTop Mountain[11] in 2005,[12] and a fatal hiker incident (from an apparent accidental fall) in 2006 that involved state search and rescue.[13] The U.S. Forest Service does not offer updated aggregated records on the official number of fatalities in the Wind River Range.
