Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of the Oregon Department of Geology and Mineral Industries publication “Geology of the Northern Part of the Wallowa Mountains of Oregon”. Originally published in 1941, this important publication on Oregon Mining has not been available for nearly seventy five years. Included are details on the geology of this unique portion of North Eastern Oregon. This is the second part of a two book series on the area. Accompanying the text are rare photographs and historic maps. 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 images might suffer from slight imperfections or minor shadows in the page background.
