The China Wall Area is a beryllium mine located in Park county, Colorado at an elevation of 8,451 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Location): LATITUDE AND LONGITUDE GIVEN FOR CENTER OF SECTION LINE BETWEEN SECTIONS 04 AND 05 ; INFO FROM LAND.ST :(1976)
Comment (Commodity): NONPEGMATITIC BERYLLIUM DEPOSITS; BERYL OCCURS AS HEXAGONAL CRYSTALS AND MASSIVE POIKILOBLASTIC GRAINS.
Comment (Production): SMALL LOT OF ORE FROM THIS AREA SOLD TO CUSTER, SOUTH DAKOTA BUYING STATION IN 1962
Comment (Deposit): THE REDSKIN STOCK IS ZONED, WITH NEARLY ALL OF THE BERYLLIUM DEPOSITS OCCURRING IN THE GRANITE-APLITE OR PORPHYRITIC GRANITE FACIES OF THE GREISENIZED REDSKIN GRANITE. EVEN THOSE DEPOSITS NOT ACTUALLY IN THE REDSKIN GRANITE ARE SPATIALLY AND GENETICALLY RELATED TO IT.
