Girls Mountain is a 6,134-foot (1,870 m) glaciated mountain summit located in the Chugach Mountains, in the U.S. state of Alaska. The peak is situated 18 mi (29 km) east of Valdez, 4 mi (6 km) north-northwest of Thompson Pass, and 2 mi (3 km) west of the Richardson Highway. Precipitation runoff from the mountain and meltwater from its glaciers drains into tributaries of the Tsina River, which in turn is part of the Copper River drainage basin.

History

The Girls Mountain toponym was officially adopted in 1964 by the U.S. Board on Geographic Names after being named in 1963 by Austin Post of the United States Geological Survey. The name was suggested by the International Geophysical Year benchmark, "Station Girls, 1957", cemented into the mountain's bedrock summit.^[3] The first ascent of the peak was made in 1957 by Austin Post and USGS party who placed the benchmark.^[3]
