Part I. Geology and Ore Deposits of the Myers Creek Mining District: Part Ii. Geology and Ore Deposits of the Oroville-Nighthawk Mining District (Paperback) (ISBN-13: 9781145499232)

This detailed geological survey, "Part I. Geology and Ore Deposits of the Myers Creek Mining District. Part II. Geology and Ore Deposits of the Oroville-Nighthawk Mining District," by Joseph Bertram Umpleby, offers a comprehensive analysis of two significant mining regions. Originally published in 1911, this report provides invaluable insights into the geological formations, ore deposits, and mining activities prevalent in these districts during the early 20th century.

Umpleby's meticulous research covers the geological structure, mineral composition, and the economic potential of the ore deposits found in both the Myers Creek and Oroville-Nighthawk areas. This historical document is a crucial resource for geologists, historians, and anyone interested in the mining history of the Pacific Northwest. The study's enduring value lies in its detailed descriptions and scientific observations, making it an essential addition to any collection focused on economic geology and regional history.
