Where to See Evidence of Glaciers
Mammoth Hot Springs: Thermal kames exist in this area. Mount Everts and Bunsen Peak were both overridden by ice. The top of Sepulcher peeked above the Pinedale ice.

Swan Lake Flat: These meadows and wetlands formed after the glaciers retreated. Electric Peak, to the northwest, was also carved by glaciers.

Norris Geyser Basin: Several high peaks in the Gallatin Mountains were above the Pinedale ice cap.

Madison Valley, west of Seven Mile Bridge: Glacial moraines, glacial outwash, and recent Madison River deposits can be seen.

Fountain Flats: The Porcupine Hills and Twin Buttes are thermal kames.

Upper Geyser Basin: Volcanic rocks and ice-water contact deposits. Deposits underlying this and other area geyser basins store the water necessary for geysers to occur and allow the water to percolate up from depth.

Hayden Valley: The valley is covered with glacial till left from the most recent glacial retreat. It also has a variety of glacial and ice-water contact deposits. This glacial till contains many different grain sizes, including clay and a thin layer of lake sediments that do not allow water to percolate quickly into the ground. Thus, Hayden Valley is marshy.

Tower Fall area: North of Tower Fall, sediments between layers of basalts may show evidence of the oldest known glaciation in Yellowstone. Plus, huge boulders (known as erratics) from the last major glaciation rest atop the youngest basalt.

Lamar Valley: Huge boulders and ponds between the Lamar and Yellowstone rivers were left by melting glaciers, as were several moraines. Other ponds are within post glacial landslides.
