Abstract: This map data was compiled for the purpose of comparing multiple Animas River
Watershed Abandoned Mine Lands Project datasets such as geophysical, biologic,
remote sensing, and geochemical datasets in a geologic context.

This dataset represents geology compiled for the upper Animas River Watershed
near Silverton, Colorado. The source data used are derived from 1:24,000,
1:20,000, 1:48,000 and 1:250,000-scale geologic maps by geologists who have
worked in this area since the early 1960's.

This product consists of seven vector coverages. These separate coverages
include the geology, faults, veins, andesite dikes, dacite dikes, rhyolite
dikes, and San Juan Caldera topographic margin.
