The Sierra Club's Andy Bessler worked on three significant environmental/cultural campaigns to protect important Native American sacred lands and shutdown several mining operations in Arizona and New Mexico. The campaigns included the shutdown of the White Vulcan Pumice Mine to protect the San Francisco Peaks, the Fence Lake Coal Mine to protect Zuni Salt Lake and the Black Mesa Coal Mine to protect Black Mesa.
