Hydraulic mining in Burke and Mcdowell counties in the 1850s was limited by the elevation of the reservoir on Pilot Mountain which straddles the county line. Water from creeks miles away was channeled and flumed to the reservoir on Pilot Mountain, all by gravity. Headwall elevations of the mine gradually descend with distance from the pond. This mine may have been worked more than once when pumping water became possible using steam power. This is Silvermine Creek. Hydraulic mining put the mud in near by Muddy Creek.
