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
Climatic warming since the end of the Little Ice Age has resulted in substantial glacier ice loss around the world. Most glaciers have undergone thinning and many exhibit retreat at their margins. Glacier loss triggers a cascade of hydrological and ecological effects that impact plants, animals and can create human hazard and economic hardship. USGS scientists are using a variety of methods...
Glacier Monitoring Studies
The purpose of the CCME's glacier monitoring studies is to systematically monitor changes in Glacier National Park’s namesake glaciers and to determine the causes of changes, assess their ecological and hydrological effects, and predict future changes and effects.

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...
Developing a mechanistic understanding between recent climate patterns and Aquatic Vital Signs in the Greater Yellowstone Network
The National Park Service Inventory and Monitoring program was established to provide park managers with a broad understanding of the status of park resources using the best available science. This program acknowledges that NPS managers are confronted with complex challenges associated with the management of dynamic landscapes responding to multiple, interacting drivers of change. To provide...
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...
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...
The ecology, behavior, and conservation of migratory birds
U.S. Geological Survey research contributes to conservation measures and improved management of migratory bird populations and their habitats across the United States. Migratory birds provide ecosystem benefits that include pest control, pollination of plants and serve as food sources for other wildlife. They are also a source of recreation for millions of bird watchers and enthusiasts who...
RARMI: Northern Rocky Mountain Science Center (NOROCK) Apex Sites
In contrast to RARMI study areas in Colorado that have 10 or more years of records of continuous population monitoring, there are fewer long-term datasets for amphibian populations in the northern Rocky Mountains. The exception is an ongoing study of Columbia spotted frogs at Lodge Creek, Yellowstone National Park. Three other long-term research and monitoring areas have been established in...
RARMI: Fort Collins Science Center (FORT) Apex Sites
FORT is monitoring populations of amphibians at three apex sites using capture-recapture methods. Our goal in monitoring populations is to detect fluctuations in population size, sex ratio, survival, and recruitment. Through long-term monitoring, we can also address breeding phenology in relation to elevation, weather, and climate. Other specific questions can be asked about issues such as...
COMPLETED: Using thermal imagery to assess wolf hairloss from sarcoptic mange
Researchers at NOROCK and their partners used thermal cameras at the Grizzly and Wolf Discovery Center in Montana to assess the amount of heat lost under a range of environmental conditions with and without hair. These methods help scientists better understand how mange operates in wild wolves throughout the Greater...

Dead Horse Point
A USGS scientist skis in to Dead Horse Point on Going-to-the-Sun Road in Glacier NP.
Heavy equipment remove snow and debris from Going-to-the-Sun Road.
It requires heavy machinery to remove snow and debris along the road. In this image, crews are removing 20+ feet of snow from the Rim Rock area near Logan Pass along the Goin-to-the-Sun Road.

This image is a High Resolution Orthoimagery, 6-inch spatial resolution, Lancaster County Dataset, taken in April 2007. High Resolution Orthoimagery looks like a photograph but any distortions caused by the tilt of the camera or topography of the land have been removed, so orthoimages are geospatially accurate and can be used as maps.
