Scope and Content Note
The Lehi F. Hintze Geological Reconnaissance Maps of Oregon consist of geologic maps prepared and assembled by Hintze for much of the state of Oregon. Most of the maps are compilations of published geologic mapping, unpublished geologic mapping done by graduate students at Oregon State College and the University of Oregon, and mapping by Hintze. The maps in Series III are published geologic maps, many of which have been annotated by Hintze. The maps reflect geologic mapping done from the mid-1930s through the 1950s. Most of the maps are hand-colored and have copious annotations indicating the sources of the information or noting questions or corrections. Some of the maps include cross sections. The maps vary in scale from 1:24,000 to 1:400,000; most of the maps are 1:62,500 or 1:125,000 scale.
In addition to mapping done by Hintze, the maps document geologic mapping done by Edwin T. Hodge, W.D. Wilkinson, Howel Williams, William H. Taubeneck, and Robert G. Coleman.
