Hazards

Encountering bears is a concern in the Wind River Range.^[6] There are other concerns as well, including bugs, wildfires, adverse snow conditions and nighttime cold temperatures.^[7]

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,^[8] 2007 (involving an experienced NOLS leader),^[9] 2015^[10] and 2018.^[11] Other incidents include a seriously injured backpacker being airlifted near SquareTop Mountain^[12] in 2005,^[13] and a fatal hiker incident (from an apparent accidental fall) in 2006 that involved state search and rescue.^[14] The U.S. Forest Service does not offer updated aggregated records on the official number of fatalities in the Wind River Range.
