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.

Impacts of Disease on Wolves in Yellowstone National Park

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...

Swiftcurrent Glacier 1910 - 2016

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.

Grinnell Glacier 1938 - 2016

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.

Grinnell Glacier 1911 - 2016

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...

Grinnell Glacier, circa 1888-2016

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.

Land Treatment Digital Library

The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The...

Science in Glacier National Park

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...

Reconstructing Flow History From Riparian Tree Rings

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...

Watershed Contamination from Hard Rock Mining

Since 1986, the USGS Hard-Rock Mining Toxic-Substances Hydrology Project has focused on metal transport in streams affected by mining. Tracer-injection studies in St. Kevin Gulch, near Leadville, Colorado, helped the USGS design methods to characterize loading from mining activities on a watershed scale. Tracer-injection studies were done in 1995, in support of the planning needs of ederal...

Land Treatment Digital Library (LTDL)

The Land Treatment Digital Library (LTDL) was created by the USGS to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales.

Data Entry Module for the Land Treatment Digital Library (LTDL)

This software allows agencies, organizations, and individuals to download an empty, stand-alone Land Treatment Digital Library database to individual or networked computers. Data entered in these databases may be submitted to the USGS for possible inclusion in the online Land Treatment Digital Library (https://ltdl.wr.usgs.gov).
