The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy...
In 1995 and 1996, wolves were reintroduced into the Northern Rockies where they have since established and spread. Within Yellowstone National Park, one of the core protected release sites, the unmanaged population steadily increased to high densities, producing a large wolf population susceptible to infections such as canine parvovirus (CPV), canine distemper virus (CDV) and sarcoptic mange...
Bighorn sheep populations are often impacted by outbreaks of pneumonia that are suspected to come from domestic sheep and goats.
Researchers at the USGS are working on developing new quantitative methods to study disease dynamics in wildlife systems as well as systems at the wildlife-domestic-human interface. Much of our work focuses on how host population structure affects disease invasion, persistence and control in wildlife disease systems. We tackle these issues with a combination of simulation and statistical...
Brucellosis is a nationally and internationally regulated disease of livestock with significant consequences for animal health, public health, and international trade.
In 1910, the year Glacier National Park was established, Swiftcurrent Glacier filled this hanging valley just below the Continental Divide. In 2016, it is obvious where the glacier has receded from the cliff edge and lateral moraine that once defined its extent. Swiftcurrent fire lookout can be seen on top of the pyramid-shaped mountain in the 2016 photo.

Notice the man standing on the glacier in the center of the historic photograph. The figure lends a frame of reference to the photo pair, allowing the viewer to more easily interpret the depth of ice and the loss of volume when compared to the 2016 image.
Please respect the photographer: When using these photographs, please credit the photographer and source (eg. T.J. Hileman,...
The historic image shows how the upper bench of ice flowed into the main body of Grinnell Glacier. By the early 1920s, the glacier’s volume had been reduced to the point that the two pieces became disconnected. The upper bench, considered a separate glacier, was later renamed The Salamander Glacier for its salamander-like profile against the headwall. The Continental Divide runs along the...
This historic image is one of the oldest images re-photographed among the collection. The massive wall of ice that constituted the terminus of Grinnell Glacier has receded beyond view from this point. Each summer thousands of hikers take the well-worn trail to be rewarded with the sight of the remnant Grinnell Glacier and Upper Grinnell Lake.
Please respect the photographer: When...
Glacier National Park (GNP) is considered a stronghold for a large diversity of plant and animal species and harbors some of the last remaining populations of threatened and endangered species such as grizzly bear and bull trout, as well as non threatened keystone species such as bighorn sheep and black bear. The mountain ecosystems of GNP that support these species are dynamic and influenced...
Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We also use downscaled climate...
The retreat of glaciers in Glacier National Park, Montana, has received widespread attention by the media, the public, and scientists because it is a clear and poignant indicator of change in the northern Rocky Mountains of the USA. In 2017 the...

Area of the Named Glaciers of Glacier National Park (GNP) and Flathead National Forest (FNF) Derived from Aerial and Satellite Imagery, 1966, 1998, 2005, 2015
These data represent a time series of the 37 named glaciers of Glacier National Park, MT, USA and two named glaciers in the Flathead National Forest.
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.
The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and Fall.
The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
The Flattop Mountain SNOTEL (SNOw TELemetry) station is one of nearly 600 similar stations operated throughout the western United States by the Natural Resources Conservation Service (NRCS, U.S. Department of Agriculture). These stations measure and record Snow Water Equivalent (SWE), which is the weight of snow water equivalent to inches of water. Most SNOTEL sites also measure temperature an
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
