Economic Geology Collections


The AHC's Economic Geology collections document the history of hard mining and petroleum. While many of these collections focus on Wyoming, our holdings have global significance. The Anaconda Geological Documents Collection, in particular, has been described as one of the largest and most signicant historical collections related to mining.

Some of our prominent Economic Geology holdings are detailed below. Additional holdings can be located by searching our online inventories (select University of Wyoming as the institution), or by viewing Frequent Searches for Economic Geology Collections in the UW Catalog. A comprehensive list of collections can also be found in the AHC's Guide to Economic Geology Collections.
