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 from footbridge 1887-2008

Among the earliest photos of Grinnell Glacier, this 1887 image shows the immense extent and depth of the glacier at the turn of the 20th century. The glacier has responded to temperature and precipitation in the past 100 years, resulting in it’s obvious reduction in size.

Grinnell Glacier from trail 1900-2008

In 1900 Grinnell Glacier’s mass filled the cirque basin. This early photo shows the glacier’s height along the headwall and how it was once joined the upper ice portion, now called The Salamander.

Clements Glacier, 1914 - 2010

Clements Glacier displayed crevasses in 1914, but in 2010 it is merely a perennial ice mass. Each summer, thousands of visitors pass by the steep moraines sculpted by this glacier as they hike from Logan Pass to Hidden Lake Overlook. The trail is visible along the left side of the 2010 photo.

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.

February 23, 2016

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.

February 23, 2016

Telemetry by foot

Once a grizzly bear is radio collared, biologists can track its movements with telemetry on foot.   

February 23, 2016

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. 

February 23, 2016

Culvert trap and bait

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

February 23, 2016

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. 

February 23, 2016

An immobilized bear.

Biologists use a syringe pole to immobilize the captured grizzly bear.  It takes approximately 10 minutes for a bear to become immobilized.  

February 23, 2016

Ready to remove from the trap

Biologists have immobilized the bear and prepare to lift it out of the trap and onto the tarp for data collection.  Once on the tarp the bear is easier to move. 

February 23, 2016

Preparing for collection of samples

A biologist prepares to collect biological information from the bear they have captured.  Biologists collect hair samples for genetic analysis, weigh the bear,  and gather numerous measurements of the body, such as the head, paws, claws, teeth, etc.  Overall condition of the bear is assessed as well, including a body fat measurement.

February 23, 2016

Getting the bear's weight

One of the first measurements taken is the bear’s weight using a quadpod and electronic scale. 

February 23, 2016

Getting set up

Biologists are very careful to keep the grizzly bear under shade and protected from the elements while they collect biological data.  Vital signs are monitored throughout the handling period.
