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

Comments
Comment (Location): ABOVE AND NORTH OF RALSTON CREEK POSSIBLY AROUND CARR ST. AND 66TH AVE.
Comment (Production): PARKER STATES THAT RALPH MINGES (ORIG. REF. TO PERS. COMM.) ESTIMATED THE GRAVEL HAD VALUE OF 40?/YD IN COARSE GOLD
Comment (Deposit): PARKER STATES THAT ALTHOUGH THE SURFICIAL UNIT CORRELATES WITH SLOCUM LEVEL, THE HIGH LEVEL OF THE GRAVELS MAY BE REMNANTS OF VERDOS ALLUVIUM. LINVALL'S MAP SHOWS COLLUVIUM OVERLYING DENVER FM (PALEOCENE) IN THIS AREA (PRESUMABLY T3S, R70W) BUT SMALL REMNANTS OF TERRACE/PEDIMENT GRAVEL MAY BE PRESENT
