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

Comments
Comment (Location): LOCATION GIVEN FOR CARD IS GARDNER ADIT PORTAL; UTM OF KENTUCKY-UTAH PORTAL IS 4497100N, 449100E; COPPER KING SHAFT AT 4495800N, 449100E; CLARK TUNNEL AT 4494700N, 448600E; NEW SENSATION TUNNEL AT 4494900N, 448800E; MANNAHANSETT TUNNEL AT 4494700N, 448900E. PROPERTIES WERE CONSOLIDATED IN 1928 TO FORM THE KENTUCKY-UTAH GROUP. PRIOR TO CONSOLIDATION THE INDIVIDUAL MINES INCLUDED THE WOODLAWN MINE, BIG COTTONWOOD COALITION, AND COPPER KING MINE. ; INFO FROM LAND.ST :1983
Comment (Production): TOTAL PRODUCTION FOR GROUP PRIOR TO 1928 WAS ABOUT 30,000 DOLLARS. WOODLAWN MINE DURING PERIOD FROM 1915 TO 1923 PRODUCED 406 TONS OF 17.61 OZ AU, 11,065 OZ AG, 3965 LBS CU, 97,253 LBS PB, AND 21,141 LBS ZN.
Comment (Development): WOODLAWN MINE PRODUCED & DEVELOPED FROM 1904 THROUGH LATE 1920'S. LATER DEVELOPMENT WAS THROUGH THE DEEP KENTUCKY-UTAH ADIT WITH LIMITED PRODUCTION.
Comment (Deposit): MINERALIZATION APPEARS TO BE GENETICALLY RELATED TO INTRUSIVES. WORKINGS EXPLORED NUMEROUS NORTHEAST STRIKING FISSURE VEINS WITH MINOR ASSOCIATED REPLACEMENT IN LIMESTONE. MINOR CU-AU BEARING SKARN DEPOSITS FOUND DEEP BENEATH WOODLAWN MINE IN KENTUCKY-UTAH ADIT.
Comment (Workings): KENTUCKY-UTAH ADIT IS ABOUT 9000 FT LONG, WOODLAWN MINE WORKINGS TOTAL 4400 FT. NO MAJOR STOPES
Comment (Geology): MINERALIZATION OCCURS IN MAXFIELD LIMESTONE, GARDISON LIMESTONE, DESERT LIMESTONE, AND HUMBUG FORMATION
Comment (Commodity): HIGHLY VARIABLE ORES, CU-RICH, PB-RICH, AND ZN-RICH ORES ALL PRESENT
Comment (Deposit): Discovery Year: LATE 1800'S
