First published in 1923, it has been unavailable since those days and sheds important light on the mines and mineral deposits of the Creede Mining District in Mineral County, Colorado. Included are geologic details on dozens of mines in this important mining Colorado region. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.
