In 1969 and 1970, the Industrial Minerals Company excavated additional pits and recovered approximately 436 tons of ore grading 53% CaF. The feature resulting from a large meteorite impact is known as the Des Plaines Disturbance. Hicks Dome, a cryptovolcanic feature in the northwestern part of the Fluorspar Area Fault Complex, played a key role in the structural evolution of the region. A peak's prominence, also known as topographic prominence or relative height, is a measure of how distinct a peak is from other peaks. 2 hole was drilled to 2,485 feet, and the core was composed of breccia cemented by white calcite, with sparse fluorite in the upper portion, but fluorite averaged between 2% and 8% from 2,000 to 2,240 feet. 615 E.
