Shrinking Teton Glaciers

In the past 40 years, the Teton, Teepee, and Middle Teton glaciers on these peaks have lost 25 percent of their total surface area. Glaciers show that climate changes. They serve as icy reservoirs, accumulating snow and ice during wet, cool years when people need less water and releasing more water into rivers in warm, dry years. Water runoff from the Teton Range provides wildlife habitat, recreational opportunities, and irrigation for crops along the Snake River in Idaho, Oregon, and Washington.
