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.

Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

EcoFlows: Understanding Streamflow Dynamics in Small Mountain Streams

The WY-MT WSC is collaborating with the Northern Rocky Mountain Science Center to understand the dynamics of streamflows in small, mountain streams during the course of the year, and to describe the amount of variability associated with those measurments. These findings will assist fisheries biologists who are researching temperature and streamflow effects on cutthroat trout and will help...

Grinnell Ridge, Gem & Salamander Glaciers 1910 - 2017

In 1910, Morton Elrod documented how Grinnell Glacier’s mass filled the basin and how the glacier was then joined with the ice apron we now call the Salamander (right). Close inspection of Gem Glacier (top-center) reveals a loss of thickness / volume over the past 107 years as well.

Electron microprobe data for monazite and xenotime used in consideration of gold deposit formation models

The genetic origin of many gold deposits, including Pogo in Alaska, remains controversial with questions as to whether they formed due to magmatic-hydrothermal or metamorphic-hydrothermal fluids. Gaining a better understanding of the formation mechanisms for these deposits is critical for defining proper exploration criteria in gold-bearing regions and production within these deposits. Monaz...
