This publication contains summaries of placer mining operations active between 2007 and 2009. Although formatted, summaries have not been edited for this publication. The maps were generated from an ArcGIS digital compilation, which was converted into a publishable format through Adobe Illustrator. Information about the active placer operations and related geology was derived from survey forms which were completed by placer miners, and from field visits. Although we have made our best efforts to include all active operations and to be as accurate as possible, there may be some omissions and errors and we apologize for those. Summaries are arranged in sections by drainage basin, with corresponding maps and photos included.
