Description

The Summitville gold mine in the San Juan Mountains of southwestern Colorado was the focus of extensive public attention in 1992 and 1993 due to environmental problems stemming from open-pit mining. Summitville catalyzed national debates about the environmental effects of modern mining, and became the focus of arguments for proposed revisions to the 1872 Mining Law governing mining on public lands. In early 1993, USGS scientists and their partners began a multidisciplinary investigation to provide needed scientific information on Summitville's environmental problems and downstream environmental effects. The Summitville investigation shows how geologic and geochemical information can be used in future mining operations to more effectively anticipate and mitigate potential environmental effects of mining for metals.
