Big Sandy Mountain

Big Sandy Mountain (12416 ft) is located in the southern Wind River Range in the U.S. state of Wyoming. Big Sandy Mountain sits along the Continental Divide, less than 1 mi southeast of Dog Tooth Peak.

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

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