Description
Geologic map of the Iditarod C-3 Quadrangle, Alaska, Professional Report 96, provides 1:63,360 geologic mapping of the Iditarod C-3 Quadrangle. The Iditarod C-3 Quadrangle lies on the eastern edge of the Kuskokwim Mountains, a maturely dissected upland of accordant, rounded ridges and broad, sediment-filled lowlands. Mineral deposits of economic significance in the area include the gold cinnabar-chromite placer deposits on Moore, Fourth of July, and Deadwood Creeks, the Broken Shovel silver-gold lode, and sand and gravel deposits in tailings along Moore Creek. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2277.
