The district, which extends into southwestern Missouri, northeastern Oklahoma, and the very southeastern corner of Kansas, was once one of the major lead and zinc mining areas in the world. From 1850 to 1950, the district produced 50 percent of the zinc and 10 percent of the lead in the United States, with production peaking between 1918 and 1941.
