Middle Teton Glacier, Alpine glacier in Grand Teton National Park, United States

The Middle Teton Glacier lies on the northeast flank of Middle Teton in Grand Teton National Park, Wyoming, at the west end of Garnet Canyon. Between 1967 and 2006 it shrank from 52 to 39 acres (21 to 16 ha), about a quarter of its surface. Its meltwater feeds streams below, including the 80 ft (24 m) Spalding Falls.

Between 1967 and 2006, Middle Teton Glacier lost about 25 percent of its surface area, shrinking from 52 to 39 acres (21 to 16 hectares). The glacier sits at the west end of Garnet Canyon, the route most climbers use to ascend Grand Teton, and its meltwater feeds Spalding Falls, an 80 ft (24 m) cascade below.

The glacier draws mountaineers and ice climbers who come to practice their skills before tackling harder routes in the Teton Range. People use this location to build confidence and test their techniques on real ice and snow.

Access is through hiking trails in Grand Teton National Park and requires proper fitness and climbing gear. Visitors should prepare for unpredictable mountain weather and attempt this location only during warmer months.

The glacier generates Spalding Falls, a waterfall that forms when meltwater flows down the northeastern slopes. This water feature shifts with the seasons and reflects how the ice directly shapes the surrounding landscape.
