Geologic map of the Kavik River area, northeastern Brooks Range, Alaska

The 1:63,360 Kavik River geologic map area consists of ~620 square miles and ties together previous DGGS mapping in the Sadlerochit and Shublik Mountains area of the western Arctic National Wildlife Refuge (ANWR) on the east and the structurally complex foothills and mountain front near the Kemik gas accumulation on the west. The map area exposes a unique intersection of North Slope stratigraphy where all three major depositional megasequences are mappable in close association (Ellesmerian, Beaufortian, and Brookian).

Top Mesozoic unconformity subcrop map, Cook Inlet basin, Alaska

This map shows the subcrop pattern of the Mesozoic rock units present at the top Mesozoic unconformity (also commonly referred to as the base Tertiary unconformity) in Cook Inlet basin, Alaska. The subcrop is projected onto the top Mesozoic unconformity depth surface of Cook Inlet basin, Alaska, published by Shellenbaum and others (2010). Publicly available geologic and geophysical data from multiple sources were collected, interpreted, and integrated into the subcrop map. Formation picks at the top Mesozoic unconformity were determined for 109 wells. Mesozoic horizons from two regional marine two-dimensional (2-D) seismic datasets (approximately 3,300 miles) were interpreted. Eight map units were established for...

Geologic Photos of Alaska

The Geologic Photos of Alaska database and online application contains photographs taken during and in support of Alaska Division of Geological & Geophysical Surveys (DGGS) projects. These photographs primarily document field sites and geomorphology statewide, usually in remote locations that are often impossible or prohibitively expensive to revisit. The database (http://maps.dggs.alaska.gov/photodb/) includes a variety of images such as field photos, photos of samples, and photomicrographs (photograph of a microscopic object) taken with the aid of a microscope.
