Economic Geology Collections


American Heritage Center

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 significant historical collections related to mining.
