Abstract
Description
The Rock River 30' x 60' quadrangle is in southeastern Wyoming in Albany, Laramie, and Platte counties. The map area is bisected by the Laramie Mountains, a north-south–trending range of uplifted Precambrian igneous and metamorphic rocks. This geologic compilation project also includes a portion of the Laramie Basin, drained to the north by the Laramie River, and the northwestern extent of the Denver-Julesburg Basin. This work was funded under USGS STATEMAP grant award G20AC00199. Mapping this quadrangle at 1:100,000-scale assists the Wyoming State Geological Survey with several mapping priorities, primarily to evaluate current and potential minerals, and edge matching and infill areas of limited existing geologic mapping.
