At a scale of 1:100,000, this map shows an uncommon level of detail for State geologic maps. Mapped rock units are primarily based on lithology, or rock type, to facilitate derivative studies in multiple disciplines.
Entry to the Atlas of Antarctic Research giving a common base map for displaying research results, data, and descriptions of projects. Layers can be viewed or downloaded as Digital Elevation Models (DEMs), digital aerial photos, and satellite images.
The Eagle quadrangle covers an area that straddles the Eagle River and Interstate 70 (I-70) and it includes the town of Eagle, Colo., which is located in the southwestern part of the quadrangle, just south of I-70 and the Eagle River, about 37 km west of
