Version 10.0 of these data are part of a larger U.S. Geological Survey (USGS) project to develop an updated geospatial database of mines, mineral deposits, and mineral regions in the United States. Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, have been digitized from the 7.5-minute (1:24,000, 1:25,000-scale; and 1:10,000, 1:20,000 and 1:30,000-scale in Puerto Rico only) and the 15-minute (1:48,000 and 1:62,500-scale; 1:63,360-scale in Alaska only) archive of the USGS Historical Topographic Map Collection (HTMC), or acquired from available databases (California and Nevada, 1:24,000-scale...

The Tri-State Mining District (TSMD) is an area encompassing portions of Kansas, Missouri, and Oklahoma in which lead and zinc mining historically occurred. To further investigate the relationship between metal contamination and unionid communities, goals of this study were as follows; 1) Conduct a reconnaissance survey of the North Fork Spring River, Spring River, Center Creek, Shoal Creek, Tar Creek, Lost Creek, and Neosho River for areas containing live unionids and/or suitable unionid habitat with the goal of identifying approximately 25 sites that warrant further quantitative assessment, 2) Conduct quantitative unionid and habitat surveys at selected sites, and 3) Compare quantitative mussel data and preliminary...
