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.

Boulder Glacier Terminus, 1913 - 2012

In the past 100 years, Boulder Glacier has been reduced to a small sliver of ice in the shadow of Boulder Peak. At the former terminus, small trees and other vegetation have become established where once there was only rock and ice.

Boulder Glacier - Chapman Peak, 1910 - 2007

Boulder Glacier as viewed from Chapman Peak in the northwest region of Glacier National Park. The historic photo shows the expansive Boulder Glacier, taken around 1910, coupled with a 2007 view of Boulder Glacier. Taken approximately 100 years apart, these images show the immense reduction in the area of Boulder Glacier. A portion of Agassiz Glacier is also visible beyond the right side of...

Boulder Glacier, 1932 - 1988

This pairing of photos from the flank of Boulder Glacier reveals a dramatic change in the 56 years between the photos. The repeat photograph was taken by Glacier National Park ranger Jerry DeSanto. Pack trips to Boulder Glacier used to include exploration of the glacier’s ice cave. The cave has long since disappeared as the glacier receded beyond this point.

Blackfoot-Jackson Glacier, 1914 - 2009

At the time the 1914 photograph was taken, Blackfoot and Jackson Glaciers were joined by their expansive margins. The 2009 photograph shows how each glacier has receded to the confines of its own cirque.

Repeat Photography Project

Repeat photography provides objective visual evidence of landscape change. USGS scientists created approximately sixty repeat photography pairs that document glacier change in Glacier National Park. These photograph pairs are available as a collection hosted by the USGS Photographic Library and are publicly available for download.  Modern (1997 to 2019) photographs were taken from precisely...

Going-to-the-Sun Road Avalanche Forecasting Program

As the most popular attraction in Glacier National Park (GNP), the Going-to-the-Sun Road traverses scenic alpine zones and crosses the Continental Divide at Logan Pass (2026m or 6,647' elevation).  The Park closes a 56km (34.8 mile) section of the road each winter due to inclement weather, heavy snowfall, and avalanche hazards. Annual spring opening of the road is a highly anticipated event...

Brief History of Glaciers in Glacier National Park

The history of glaciation in Glacier National Park spans thousands of years of glacial growth and recession, carving the steep and striking mountain features we see today. Glaciers have been present within the  boundaries of present-day Glacier National Park since as early as 6,500  years ago (Munroe and others, 2012). These modest glaciers varied in size, tracking climatic trends, but did not...

Status of Glaciers in Glacier National Park

Glaciers on the Glacier National Park (GNP) landscape have ecological value as a source of cold meltwater in the otherwise dry late summer months, and aesthetic value as the park’s namesake features. USGS scientists have studied these glaciers since the late 1800s, building a body of research that documents widespread glacier change over the past century. Ongoing USGS research pairs long-term...

Close up

The kerchief over the grizzly bear’s eyes protects it from dust and debris and reduces visual stimulation. The small tubing in its nose, known as a nasal cannula, delivers oxygen to the animal while it is tranquilized.

Assessing body fat percentage of grizzly bear

Field personnel use bioelectrical impedance to assess body fat percentage of captured bears.  The procedure is similar to how body fat is measured in humans and is based on the resistance of body tissues to the flow of a small, harmless electrical signal.  The electrical current is impeded more by fat tissues compared with tissues that are composed mostly of water, thus

A mother grizzly bear and her cub in Yellowstone National Park.

A USGS grizzly bear researcher snapped this picture of a mother grizzly bear and her cub in Yellowstone National Park. Recent research shows that fffspring of grizzly bear mothers with a history of human-bear conflicts are more likely to be involved in human-bear conflicts than offspring of mothers without a history of human-bear conflicts.
