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): THIS SITE WAS RECLAIMED BY THE MONTANA DEPARTMENT OF STATE LANDS/ABANDONED MINE RECLAMATION BUREAU IN 1987. WASTE ROCK DUMPS AND TAILINGS PONDS WERE ALMOST COMPLETELY REVEGETATED. ACCURATE ESTIMATION OF THE VOLUME OF TAILINGS WAS DIFFICULT DUE TO COVERING AND GRADING ACTIVITIES THAT OCCURRED DURING THE RECLAMATION ACTIVITIES. SPRING CREEK FLOWED ALONG THE RECLAIMED WASTE ROCK AND TAILINGS IMPOUNDMENTS. OBSERVED RELEASES TO SPRING CREEK (SEDIMENT) WERE DOCUMENTED FOR CADMIUM, COPPER, LEAD, AND ZINC. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED IN SPRING CREEK WATER SAMPLES. THE UNNAMED TRIBUTARY COMING INTO SPRING CREEK FROM THE NORTHWEST CONTAIMED ELEVATED LEVELS OF CADMIUM, COPPER, LEAD, AND ZINC. MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED FOR CADMIUM AND COPPER IN THIS TRIBUTARY.
