Satelite View

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

Comments
Comment (Environmental Factors): THERE WERE NO TAILINGS ASSOCIATED WITH THIS SITE. THERE WAS ONE ADIT DISCHARGE, BUT FIELD PARAMETER MEASUREMENTS INDICATED UNIMPAIRED WATER QUALITY. MINNEHAHA CREEK WAS LOCATED IN THE DRAINAGE APPROXIMATELY 3000 FEET BELOW THE LOWER MINE WORKINGS. NO WATER SAMPLES WERE COLLECTED BECAUSE OF THE DISTANCE FROM THE SITE AND LACK OF SURFACE WATER RUNOFF. SAMPLING DURING EARLY SPRING SNOW MELT/RUNOFF EVENTS COULD POSSIBLY DOCUMENT IMPACTS TO THE CREEK. XRF SCREENING OF STREAM SEDIMENTS INDICATED NO IMPACTS TO THE CREEK ATTRIBUTABLE TO THIS SITE. THERE WAS ONE HAZARDOUS MINE OPENING, THE UPPER ADIT. THERE WAS ONE RESIDENCE ON-SITE THAT APPEARED TO BE USED OCCASIONALLY FOR RECREATIONAL USE.
