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

Comment (Deposit): CLAIMS INCLUDED CORONA, CORONA NO. 1 AND NO. 2 ; INFO.SRC : 1 PUB LIT
Comment (Workings): CREEK-LEVEL ADIT ON CORONA NO. 1 CLAIM 370-FT. LONG TO NORTH. SOME ORE STOPED ABOVE TUNNEL ABOUT 100 FT. FROM PORTAL, NEAR OLD STOPE. 220 FT. SHAFT WITH LEVELS AT 75, 125 AND 200-FT. 50-FT. LONG ORE SHOOT WAS MINED ABOVE 75 AND 125-FT. LEVELS, FROM RAISE ON 125 FT. LEVEL, CONNECTING TO SURFACE. HANGING WALL CROSSCUT AT 200 FT. LEVEL CUT 8 IN. STRINGER ZONE. AT 42 FT., IT CUT THROUGH 11 FT. OF TALC. SEVERAL OLDER TUNNELS ON NORTH AND SOUTH SIDES OF JAIL CANYON.
