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.

Comments

Comment (Environmental Factors): THE TAILINGS WERE LOCATED WITHIN THE FLOODPLAIN OF SNOWSHOE CREEK. SOME RECLAMATION HAD BEEN DONE ON THE LOWER WASTE ROCK DUMP. THERE WERE NO ADIT DISCHARGES ASSOCIATED WITH THE SITE; HOWEVER, AN INTERMITTENT TRIBUTARY TO PERENNIAL SNOWSHOE CREEK RAN THROUGH THE SITE. THE TRIBUTARY HAD A TRICKLE OF FLOW DURING THE INVESTIGATION WHICH EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM. THE DOWNSTREAM SAMPLE IN SNOWSHOE CREEK ALSO EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FROM CADMIUM. OBSERVED RELEASES TO SHOWSHOE CREEK WERE DOCUMENTED FOR ARSENIC, CADMIUM, IRON, LEAD AND ZINC. THE MAXIMUM CONTAMINANT LEVEL EXCEEDANCE FOR CADMIUM CAN BE DIRECTLY ATTRIBUTED TO THE SITE. THE THREE OPEN ADITS AND SEVERAL STEEP, UNSTABLE WASTE PILES WERE ACCESSIBLE AND POTENTIALLY HAZARDOUS.
