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 (Location): EXACT LOCATION UNCERTAIN. HANLEY AND OTHERS (1950) GIVE LOCATION AS SEC. 06, T48N, R5W, BUT DUE TO SURVEY ADJUSTMENTS, THIS TOWNSHIP HAS NO SEC. 06; SEC. 05 ABUTS SEC. 01, T48N, R6W. ELEV AND LAT-LONG GIVEN ARE FOR INTERSECTION OF ROADWAY AND OLD RAILROAD R-O-W WITH COMMON SECTION LINE. ; INFO FROM LAND.ST :1975
Comment (Development): VIARRIAL RECOVERED BERYL CRYSTALS FROM SLIDE ROCK THAT COVERED RAILROAD TRACKS IN SPRING OF 1943.
Comment (Deposit): GIVEN THIS ESTIMATED LOCATION, FOLIATION OF GNEISSIC COUNTRY ROCK TRENDS GENERALLY NE TO NNE-SSW, DIPPING NW. PEGMATITES IN AREA TREND GENERALLY EAST-WEST TO WNW-ESE. HANLEY AND OTHERS (1950) STATE THAT THIS PEGMATITE DIPS APPROX 60 NE. BIOTITE OCCURS AS LATHLIKE CRYSTALS UP TO 2 FT LONG. HIGHLY SHATTERED DARK RED GARNET UP TO 2 INCHES IN DIAMETER OCCURS IN SEVERAL QUARTZ CONCENTRATIONS. BERYL IS LIGHT BLUE ON FRESH SURFACE AND GREENISH YELLOW ON WEATHERED SURFACES. LARGEST BERYL CRYSTAL FOUND IN SLIDE MATERIAL REPORTEDLY WAS 2 FT LONG AND 6 INCHES IN DIAMETER. NO MINABLE CONCENTRATIONS WERE FOUND.
