Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Environmental Factors): TAILINGS WERE ACTIVELY ERODING INTO THIS TRIBUTARY OF SPRING CREEK. TWO ADIT DISCHARGES WERE ASSOCIATED WITH THIS SITE, MAKING UP ALL OF THE FLOW OF THIS TRIBUTARY OF SPRING CREEK DURING MID-SUMMARY, LOW-FLOW CONDITIONS. BOTH ADIT DISCHARGES EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FOR ARSENIC. THIS TRIBUTARY TO SPRING CREEK FLOWED INTERMITTENTLY ABOVE THE ADIT DISCHARGES, AND BELOW IT FLOWED THROUGH THE WASTE ROCK AND TAILINGS. OBSERVED RELEASES WERE OBSERVED FOR ARSENIC, LEAD, AND ZINC. THE UPGRADIENT SURFACE WATER SAMPLE INDICATED THE RESENCE OF AN UPGRADIENT CONTAMINANT SOURCE.
