Until recently, a spatially explicit dataset illustrating the 21st century mining footprint for the conterminous United States did not exist. Through collaboration between the USGS Western Geographic Science Center, USGS  Earth Resources Observation and Science (EROS) Center, and SUNY Department of Forest and Natural Resources Management, surface mines within the United States have now been mapped for 2001 and 2006.
