Unified Interior Regions

Alaska

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.

USGS Transboundary River Monitoring in Southeast Alaska

The quantity and quality of streamflow in transboundary watersheds of Southeast Alaska are important to many stakeholders. Development and operation of several mines in Canada have increased the interest in current and future conditions in these watersheds. The USGS Alaska Science Center operates streamflow information stations on the Alsek, Chilkat, Taku, Stikine, and Unuk Rivers. Real-time...

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...

Beak Deformities in Landbirds

Over the past 20 years, Alaskans have witnessed a startling increase of beak deformities among Black-capped Chickadees and other species of resident birds. This disease, called avian keratin disorder (AKD), is characterized by debilitating beak overgrowth and other abnormalities of keratinized tissues. Affected birds have difficulty feeding and preening, and may suffer high rates of mortality...

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.
