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.
