Unified Interior Regions

Montana

Welcome to the Midwest Region! Our region includes 18 Science Centers in 11 States from the Great Lakes to the Dakotas, south to Missouri and Kentucky. Our streamgage network is used to monitor and assess water resources across the region. Other research focuses on fisheries and aquatic ecosystems, midcontinental plant/animal species, invasive species, wildlife disease, and energy and mining.

Jackson Glacier

At the time this historic photograph was taken in 1911, Blackfoot Glacier encompassed the current Jackson Glacier. By 1939, Blackfoot Glacier's recession had resulted in two distinct glaciers, Jackson and Blackfoot. This photo pair shows glacial recession and successive vegetation growth along Jackson Glacier's terminus.

Harrison Glacier

While difficult to quantify, this photo pair of Harrison Glacier exemplifies the loss of glacier volume. Comparison of the ice profile in the foreground of the photos shows a marked thinning of the glacier over the years,. Colorful layers of sedimentary bedrock are being exposed as the glacier recedes from the cliff bands.

Grinnell Glacier Basin 1936-2013

As Grinnell Glacier retreats, vegetation establishes itself in the newly exposed surfaces. The increase in vegetation along the moraine (center) in this pair is especially obvious.

Grinnell Glacier Basin 1936-2010

Upon close inspection of this photo pair, the viewer can appreciate the change in the volume of glacial ice that has melted from Grinnell Glacier. In the 2010 image, the glacier's terminus can be seen along the edge of Upper Grinnell Lake, a feature that did not exist in 1936.

Grinnell Glacier from Elrod's Rock and terminus

This large boulder was used by Morton Elrod and other scientists as a baseline to measure the retreat of Grinnell Glacier’s terminus. It is now referred to as “Elrod’s Rock,” and the glacier’s terminus is no longer visible from this point.

Grinnell Glacier from South Moraine

This pair of photographs from Grinnell Glacier’s southeast edge shows the dramatic change in the glacier’s volume and area. Note the glacier’s depth along the headwall and its extent at the terminal moraine in the historic photograph.

Shepard Glacier, Glacier National Park, Montana - 2005

The thick, crevassed, ice flows of historic Shepard Glacier have been diminished to less than 0.1 square kilometer in area by 2005. According to the criteria set by the USGS Repeat Photography Project, Shepard Glacier is now considered to be too small to be defined as a glacier. (Blase Reardon)
