Copies of my doctoral thesis can be requested from the University of
Wyoming Geology Library, Laramie, WY. I'm a full time
saddlemaker-silversmith now and don't have the equipment to reproduce
the text or maps. It covers the geology of the bedrock deposits.

and the Laramie Mountains, Wyoming: Ph.D. theses, Univ. Wyo., 194 p.
In the past, the library has contacted me for permission to make a
copy available to someone and it was granted. A short article on the
Sage Creek nephrite deposit was published and you can get the
reference by searching "Sage Creek Nephrite"
