Snow and Avalanche Research

Since 1991, CCME staff have conducted snow surveys throughout Glacier National Park. These data have contributed to regional climate change and hydrologic models. Snowpack characteristics have also been evaluated in relation to avalanche forecasting and plowing of GNP’s Going to the Sun Road efforts. Studies of natural snow avalanches reveal connections with large-scale climate and wildfire...

Grinnell Glacier in Glacier National Park.
Date Published: April 5, 2016

Secondary Glacier Network

The Secondary Glacier Network includes six glaciers (Chaney, Grinnell, Stanton, Agassiz, Swiftcurrent, Jackson-Blackfoot Glaciers) that form a north-south transect of approx. 60 km through the region, with Sperry Glacier just south of center. While these glaciers will be monitored less frequently than the benchmark glacier, Sperry, this network will provide data about the variability of...

Sperry Glacier in Glacier National Park.
Date Published: April 5, 2016

Benchmark Glacier: Sperry

Sperry Glacier was chosen as the benchmark glacier for the glacier monitoring studies, due to the combination of its topographic characteristics, historic data, and access. Annual mass balance measurements began in 2005. Sperry Glacier joined the long-established USGS Benchmark Glacier Research program in 2013 where common field and analysis methods enable regional comparison and improved...

Glacier Research

As Glacier National Park’s namesake glaciers recede, CCME staff are monitoring many of the park’s glaciers to determine the causes of change, assess their ecological and hydrological effects, and predict future changes and effects. Intensive research to determine the mass balance of Sperry Glacier will determine whether small cirque glaciers like Sperry can serve as reliable indicators of...

Restoring Montana Pothole Wetlands - Demonstration Sites and Adaptive Management

Geologic processes from the last ice age have generated extensive areas of pothole wetlands in several Montana landscapes. The Laurentide ice sheet, originating in the Northwest Territories, provided the dominant force in eastern Montana. Similar landscapes developed in the broad valleys of western Montana through the actions of the Cordilleran ice sheet, originating in the mountains of...

Realizing the biological potential of weather radar

The modern use of field deployed remote sensors generates large amounts of environmental data on natural systems, and this benefits natural sciences. Today’s automated sensors are fast, run nearly continuously, eliminate the need for “people power”, are cost effective to operate and maintain, and monitor the environment in ways humans cannot. The US network of more than 200 weather radars, the...

American bullfrog suppression in the Yellowstone River floodplain

The American bullfrog (Rana catesbeiana) has recently invaded backwater and side-channel habitats of the Yellowstone River, near Billings, Montana. In other regions, bullfrog invasions have been linked to numerous amphibian declines (e.g., Adams and Pearl 2007). Immediate management actions may be able to suppress or eradicate localized populations of bullfrogs because they are present at low...

Conservation of native salmonids in South-Central Alaska

The proliferation of introduced northern pike in Southcentral Alaska is an urgent fishery management concern because pike are voracious predators that prey heavily on juvenile salmonids. Eradication of pike is not possible in connected freshwater networks, so managers must develop control methods that reduce pike populations to less destructive numbers. We are using field and bioenergetics...

An investigation of aquatic invasive species in pristine sites in the Greater Yellowstone Area

Aquatic invasive species (AIS) are aquatic organisms that move into ecosystems beyond their natural, historic range and cause severe and irreversible damage to the habitats they invade. Most AIS arrive as a direct result of human activity, such as boating and angling. The threat of AIS introduction is especially high in the Greater Yellowstone Area, as humans from all over the world come to...
