The peak is the emblematic geographical feature of the remote Wind River Range and is set seven miles west of the Continental Divide.[5] It is situated in the Bridger Wilderness on land managed by Bridger-Teton National Forest. Topographic relief is significant as the northeast aspect rises 3,700 feet (1,100 meters) above the Green River in one-half mile. The iconic view of Squaretop and Green River Lakes has been on the Wyoming license plate since 2016.
According to the Köppen climate classification system, Squaretop Mountain is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[6] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer. Precipitation runoff from the mountain drains north into the Green River.
The first ascent of Squaretop was made sometime before 1921 by William John Stroud (1854–1946), via the class 2 southeast ledges. Fred Beckey and Layton Kor climbed the Northeast Face in 1960.[7]

Encountering bears is a concern in the Wind River Range.[9] There are other concerns as well, including bugs, wildfires, adverse snow conditions and nighttime cold temperatures.[10]
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,[11] 2007 (involving an experienced NOLS leader),[12] 2015[13] and 2018.[14] Other incidents include a seriously injured backpacker being airlifted near SquareTop Mountain[15] in 2005,[16] and a fatal hiker incident (from an apparent accidental fall) in 2006 that involved state search and rescue.[17] The U.S. Forest Service does not offer updated aggregated records on the official number of fatalities in the Wind River Range.
