Cambria Mine

The Cambria Mine is a mercury mine located in San Luis Obispo county, California at an elevation of 1,020 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.

Mine Info

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.

Land Status

Land ownership: Private
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.

Comments

Comment (Environmental Factors): IN FEBRUARY 1992, SAMPLES WERE TAKEN IN THE CAMBRIA MINE TRIBUTARY, IN SAN SIMEON CREEK ABOVE THE TRIBUTARY, AND IN SAN SIMEON CREEK BELOW THE TRIBUTARY. WATER SAMPLED IN THE CAMBRIA MINE AND ASSOCIATED MINES TRIBUTARY CONTAINED MORE CARBONATE, CALCIUM CARBONATE, BICARBONATE, MAGNESIUM, SULFATE, TOTAL IRON, TOTAL CHROMIUM, TOTAL MERCURY, AND TOTAL NICKEL THAN THE OTHER TWO SAMPLES. SEDIMENT SAMPLES CONTAINED MORE MERCURY, IRON, NICKEL, AND CHROMIUM. THESE ELEVATED CONSTITUENTS APPEAR MINE RELATED. THE SAN SIMEON CREEK SAMPLE BELOW THE CAMBRIA MINE TRIBUTARY CONTAINED MORE TOTAL FILTERABLE RESIDUE AND SULFATE THAN IN THE SAN SIMEON CREEK SAMPLE COLLECTED ABOVE THE CAMBRIA MINE TRIBUTARY. SEDIMENT COLLECTED BELOW THE CONFLUENCE OF THE TRIBUTARY CONTAINED MORE IRON, MERCURY, AND NICKEL THAN SEDIMENT FROM ABOVE THE CONFLUENCE. THESE ELEVATED CONSTITUTENTS ALSO APPEAR MINE RELATED. SEDIMENT COLLECTED IN THE SAN SIMEON CREEK ABOVE THE CAMBRIA MINE TRIBUTARY CONTAINED MORE TOTAL FILTERABLE RESIDUE AND SULFATE THAN IN THE SAN SIMEON CREEK SAMPLE COLLETEC ABOVE THE CAMBRIA MINE TRIBUTARY. SEDIMENT COLLECTED BELOW THE CONFLUENCE OF THE TRIBUTARY CONTAINED MORE IRON, MERCURY, AND NICKEL THAN SEDIMENT FROM ABOVE THE CONFLUENCE. THESE ELEVATED CONSTITUTENTS ALSO APPEAR MINE RELATED. SEDIMENT COLLECTED IN THE SAN SIMEON CREEK ABOVE THE CAMBRIA TRIBUTARY CONTAINED ELEVATED ANTIMONY, ARSENIC, AND LEAD, INDICATING AN UPSTREAM SOURCE (POSSIBLY THE HAMILTON MINE).
