Oregon mining historian Kerby Jackson introduces us to a classic work on Oregon's mining history in this important re-issue of Bulletin 34, otherwise known as “Mines and Prospects of the Mount Reuben Mining District, Josephine County, Oregon”. Unavailable since 1947, this important publication was originally compiled by geologist Elton Youngberg of the Oregon Department of Geology and Mineral Industries and includes detailed descriptions, histories and the geology of the Mount Reuben Mining District in Josephine County, Oregon. Included are notes on the history, geology, development and assay statistics, as well as underground maps of all the major mines and prospects in the vicinity of this much neglected mining district. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As such, some type characters and photographs might suffer from slight imperfections or minor shadows in the page background.
