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.

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 Overlook 1940 - 2013

Grinnell Glacier taken from the Grinnell Glacier Overlook off the Highline Trail, Glacier National Park. The view of Grinnell Glacier taken circa 1940 shows the early formation of Upper Grinnell Lake, a proglacial lake visible at the terminus of the glacier. The 2013 photo shows a dramatic increase in the size of the lake as a result of melting ice.

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)

Fitting a radio collar

Biologists with IGBST and the National Park Service fit a grizzly bear with a radio collar.  Once a bear is radio collared, biologists can track its movements with telemetry.

Telemetry by air

Once a grizzly bear is radio collared, biologists can track its movements with telemetry via airplane.  The IGBST also used the latest telemetry technologies, which allows downloading of GPS data from the radio collar via satellites.

Culvert trap

Biologists place a culvert trap in locations that they need data from.  Field crews will set up the culvert trap and check it daily, usually in the morning, to determine if a bear has been captured.  Additionally, trap doors are checked via radio telemetry.

Culvert trap and bait

Biologists use road-killed ungulates such as deer, elk, or bison as bait in the traps.

At the capture site

At capture sites with road access, biologists drive to a trap with a bear inside to set up for collecting biological data.
