Mount Lester is a 12,342-foot-elevation (3,762-meter) mountain summit located in Sublette County, Wyoming, United States.
Description
The peak is situated in the remote Wind River Range, which is a subset of the Rocky Mountains. It is set four miles west of the Continental Divide, within the Bridger Wilderness, on land managed by Bridger-Teton National Forest. The nearest town is Pinedale, 21 miles to the southwest. Lester ranks as the 115th-highest peak in Wyoming, and topographic relief is significant as the west aspect rises 2,000 feet (610 meters) in one-half mile. The mountain's toponym, which has been officially adopted by the United States Board on Geographic Names, was in use in 1914 when published in an USGS bulletin.
Climate
According to the Köppen climate classification system, Mount Lester is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer. Precipitation runoff from the mountain drains into tributaries of the Green River.
Hazards
Main articles: Hazards of outdoor recreation and Mountaineering § HazardsEncountering 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.
