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.

Piegan Glacier

Piegan Glacier is one of the few glaciers in Glacier National Park that has not significantly changed since photographed in the 1930s.

Red Eagle Glacier

Although the 2009 photo location does not exactly match the historic photo station, a comparison of relative glacial coverage can still be made. Logan Glacier is in the foreground, while Red Eagle Glacier sits beneath the pyramidal peak that bears the same name. It appears that these two glaciers were joined at the time the historic photo was taken, but recessed into their own basins as time...

Bighorn Sheep in and near Glacier National Park

USGS collected GPS data as well as genetic and other samples on over 100 bighorn sheep east of the Continental Divide in Glacier National Park, Waterton National Park, and the Blackfeet Reservation. Bighorn sheep across the west are vulnerable to disease such as pneumonia. We are therefore working to improve our understanding of bighorn sheep movements, approaches for monitoring bighorns, and...

Ecology of Elk on Department of Interior Lands in Southwest Wyoming

Between 2005 and 2010, we radio- collared 61 female elk (Cervus elaphus) on Fossil Butte National Monument and 12 female elk near Cokeville, Wyoming, slightly northwest of the Monument, all from the West Green River herd. We are using the 209,250 locations from these elk to identify seasonal distribution patterns, evaluate habitat use, and assess factors influencing the timing of migration.  ...

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.

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)
