In 1889, David Eccles chartered the Oregon Lumber Company, an organization that produced many mills and railways and whose influence was felt from Salt Lake City to Northern California and Idaho. Through family connections, Eccles was also involved with many other logging enterprises, and he influenced the growth of the Inter-Mountain region as well as the Pacific Northwest. Sumpter Valley Logging Railroads is a pictorial history of the Oregon operations, focusing on the operations along the Sumpter Valley Railway. It explores the rails, mills, and people, as well as the logging practices of a bygone era.
