Teton Glacier

Teton Glacier is the largest of Grand Teton National Park’s twelve named glaciers and one of 37 glaciers in Wyoming. It lies below the north face of Grand Teton in a high alpine basin between Grand Teton, Mount Owen, and Teewinot Mountain. In 1971, it measured about 3,500 feet long and 1,100 feet wide, showing its substantial scale within the Teton Range. Like many Rocky Mountain glaciers, it has shrunk in recent decades. Between 1967 and 2006, its surface area declined by roughly 14 to 20 percent, making it a notable visible sign of environmental change in the range.
