Eagle Airborne Magnetic and Radiometric Geophysical Survey

The Eagle airborne magnetic and radiometric geophysical survey covers parts of the Charley River, Eagle, and Tanacross quadrangles near Eagle, Alaska (fig. 1). Magnetic and radiometric data were collected with a fixed-wing aircraft May 24 to June 27, 2021 by MPX Geophysics LTD. A total of 26,926 line kilometers were collected covering 9,731 square kilometers. The magnetometer was mounted to a rear-facing fixed boom (tail stinger). The radiometric crystals were located in the cabin of the aircraft. The Eagle survey was flown with a line spacing of 400 meters (m) and a mean ground clearance of 330 m. The data, as well as additional metadata, are available from the DGGS website: https://doi.org/10.14509/30755. USGS...

Alaska Resource Data File (ARDF)

The Alaska Resource Data File (ARDF) is a database of mines, prospects, and mineral occurrences in Alaska. It contains information compiled from published and unpublished sources from industry, U.S. Bureau of Mines (BOM), U.S. Geological Survey (USGS), and other government and private sources. ARDF is not a mining claims database. ARDF is mainly focused on metallic commodities. Common industrial minerals or commodities, such as sand, gravel and crushed stone, and limestone are not included in ARDF, nor are energy minerals such as peat, coal, and oil and gas. However, uranium, thorium, and rare earth elements, as well as some high unit value industrial minerals, such as barite, jade, graphite, and gypsum, are included....

Digitized Legacy Maps of Surficial Geology and Morphology of the Central Arctic Coastal Plain, Alaska

This dataset represents a digitized version of the Rawlinson 1993 surficial geologic map of the Flaxman Island and Beechy Point quadrangles, and portions of the Mount Michelson and Harrison Bay quadrangles at 1:63,360 scale. In this newly digitized version of the map, the original maps were scanned, georeferenced, and projected into GIS. Approximately 100-200 typographic and labelling errors from the paper version were corrected with inputs from the original author (corrections completed in 2024). However, this digitized product still adheres to the 1993 interpretation of the surficial geology. Original descriptions of the map units can be found with the 1993 publication (https://doi.org/10.14509/2484). The original...
