Teepe Glacier regression

Photos of the Teepe Glacier from August 2016, September 2021 and September 2022 show the glacier’s retreat over time. Now park officials are saying the glacier is gone — at least on the surface. They wonder whether more ice exists below the rock.

At about 9,000 feet, Simeon Caskey paused to refill his water bottle, making good use of a spring bubbling out of the rock near the Platforms, a campground midway up Garnet Canyon.

“This is probably coming out of Teepe,” Caskey said.

The Unites States Geological topographic quadrangle map from 2021 shows the Teepe Glacier still present just northwest of Disappointment Peak in Grand Teton National Park.

Middle Teton Glacier study

Simeon Caskey, Grand Teton’s physical science branch chief, scrambles through a boulder field while making his way up to the Middle Teton Glacier on Sunday. Between 2016 and 2021 the Middle Teton Glacier lost 1.6 meters of ice, on average, across survey points in the Granite Canyon ice mass.
