Grinnell Glacier from Mount Gould, 1938 - 1981 - 1998 - 2013

Oblique view of Grinnell Glacier taken from the summit of Mount Gould, Glacier National Park. The relative sensitivity of glaciers to climate change is illustrated by the dramatic recession of Grinnell Glacier while surrounding vegetation patterns remain stable. To download images, select the Multimedia tab.

Grinnell Ridge, Gem & Salamander Glaciers 1910 - 2017

In 1910, Morton Elrod documented how Grinnell Glacier’s mass filled the basin and how the glacier was then joined with the ice apron we now call the Salamander (right). Close inspection of Gem Glacier (top-center) reveals a loss of thickness / volume over the past 107 years as well.  To download images, select the Multimedia tab.

Clark Fork Water-Quality Monitoring

The U.S. Geological Survey (USGS) has collected water-quality samples from selected stream sites upstream from Missoula since 1985. Sampling was initiated in response to elevated trace-element concentrations and the designation of areas in the upper Clark Fork basin by the U.S. Environmental Protection Agency (USEPA) as National Priorities List...

Hydrologic Characterization of Potential Sites for Restored and Constructed Wetlands, Montana

Projects conducted by the Montana Department of Transportation (MDT) sometimes result in unavoidable impacts to wetlands and other aquatic habitats. To compensate for these impacts, MDT mitigates the loss of wetlands by providing replacement wetlands within the watershed.

Establishment of a baseline groundwater monitoring program in an area identified for energy development on the Blackfeet Reservation, Montana

As a result of energy development, the Blackfeet Environmental Office has developed a groundwater monitoring program specifically focused on the Cut Bank Creek watershed of the Blackfeet Indian Reservation. The addition of groundwater data to an existing surface-water monitoring program will help the Blackfeet Tribe develop a more complete understanding of the current conditions of their water...

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Delineation of brine contamination in and near the East Poplar oil field, Fort Peck Indian Reservation, northeastern Montana

Brine is a byproduct of crude oil production. Handling and disposal of brine during the last 50 years in the East Poplar oil field has resulted in contamination of not only the shallow Quaternary aquifers, but also the Poplar River. Previous investigations have documented and partially delineated the extent of brine contamination in the East Poplar oil field during the early 1990s...

Williston and Powder River Basins Groundwater Availability Study

The development of two nationally important energy-producing areas, the Williston structural basin (containing the Bakken Formation) and Powder River structural basin, provide a critical opportunity to study the water-energy nexus within a groundwater context. Large volumes of water are needed for energy development in these basins. The hydraulically connected aquifers in the...

Hydrologic Assessment with an Emphasis on Water Quality within the Lame Deer Creek Watershed, Northern Cheyenne Indian Reservation, Montana

The Lame Deer Creek watershed of the Northern Cheyenne Reservation in southeastern Montana encompasses about 82 square miles and is home to the community of Lame Deer. Local water resources within the Lame Deer Creek watershed include Lame Deer Creek and groundwater within unconsolidated sediments and bedrock aquifers. In 2017 the U.S. Geological Survey, in cooperation with the Northern...
