UNCOMPAHGRE PRIMITIVE AREA, COLORADO.

A mineral-resource study was made of that part of the Uncompahgre National Forest, Colorado constituting the officially designated primitive area. Because the primitive area and its southern border zone contained operating mines producing gold, silver, copper, lead, zinc, and minor amounts of a few other metals, and had been a part of a highly productive mining region, the area was concluded to have large segments of both probable and substantiated mineral-resource potential. No energy resources were identified in the study.
