Description
SCARCE ITEM!! GREAT COLOR MAP!! ONLY ONE AVAILABLE!!It is USGS Bulletin 1121-E,
Geology of the Nefsy Divide Quadrangle, Crook County, Wyoming
. Published in 1963, this is a pretty scarce item! This bulletin consists of a 52-page book, a full color map and a sheet of strat columns of the formations. This area is south of Devil's Tower, west of Sundance, and consists mostly of
relatively
flat lying sedimentary rocks of Triassic, Jurassic, and Cretaceous rocks.
The book covers the geology in detail, with descriptions of the formations.. The map is colorful, comes with a couple cross sections at the bottom, and really brings the geology to life.
This area had some uranium mining in the north, plus some coal and bentonite mining in some other areas. The uranium location is given in detail, so should be easy to find. A couple interesting uranium minerals were noted in the area:
Tyuyamunite
Carnotite
A nearby area just to the west of the map area is discussed where some larger uranium deposits were discovered. The
Carlile mine
was a significant producer in that area. It's location is also given in detail.
This is a cool old report that might lead you to some colorful uranium minerals. Both of those listed are bright yellow minerals. This would be great item for a mineral collector, or really anyone that is interested in this part of Wyoming, or maybe some uranium prospecting.
Expert packing assured. The recent increase in postage rates was pretty big. As a result, Media Mail is now my default shipping method to keep shipping affordable.
