Location: Nicholas County, West Virginia; Ramp Run Surface Mine #1, located about 12 miles north of Summersville, West Virginia. Turn west off route 19 north of Summersville onto Spruce Run Road. Follow it about 7 miles. It is now mostly reclaimed, but there is still some good collecting along the exposed rock rip-rap outslope of the sediment ditch along Buffalo Creek.
