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.

Probability of Streamflow Permanence (PROSPER)

PRObability of Streamflow PERmanence (PROSPER)

Rivers and streams are constantly changing. Streamflows can change throughout the year and between years due to snowmelt, precipitation, diversions, and return flows. For many streams, these fluctuations determine whether a stream has year-round flow or not. PROSPER is a project initiated to better understand what causes these fluctuations...

Bridge Scour in Montana

Bridge scour is the erosion of streambed material away from pier foundations and abutments and is the leading cause of bridge failure in the United States (Richardson and Davis, 2001). Since the early 1990s, the U.S. Geological Survey (USGS) and the Montana Department of Transportation (MDT) have had a cooperative bridge scour project in Montana.

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 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.

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...

The National Map Small-Scale Collection

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.
