Satelite View

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

Comments
Comment (Deposit): SANDY, UNCONSOLIDATED BED OVERLAIN BY TUFF AND GRAVEL. ANOTHER BED OF THIS MATERIAL MORE THAN 8 FT THICK LIES ABOUT 1000 FT NE, EXPOSED FOR 700 FT ALONG A STEEP BANK, BUT IT CONTAINS MORE CARBONATE THAN THE MAIN DEPOSIT. ASH IS LIGHT GREY TO WHITE, FINE-GRAINED (0.1-0.3 MM), ANGULAR AND FRIABLE, BUT STANDS IN VERTICAL WALLS. IT IS COMPOSED OF CLEAR VOLCANIC GLASS WITH MOSTLY LESS THAN 10% QUARTZ AND FELDSPAR FRAGMENTS. A FINE CARBONATE DUST OCCURS EVEN IN THE MOST FRIABLE MATERIAL, AND SOME, ESPECIALLY IN THE NORTHERN DEPOSIT, IS PARTIALLY CEMENTED BY CARBONATE.
