Mine Info

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): ALONG EAST TIMBERLAKE CREEK AND UNNAMED TRIBUTARIES. ELEV AND LAT-LONG GIVEN ARE FOR EXCAVATION IN SW SE 13 ; INFO FROM LAND.ST :(1974)

Comment (Development): JAMES GOOLDY, WHO HAD BEEN INVOLVED WITH DISTRICT'S DEVELOPMENT SINCE 1894, WAS GENERAL MANAGER OF TIMBERLAKE MINING AND DEVELOPMENT CO. ABOUT 1903, HE AND COMPANY DIVERTED WATER FROM SLATER CREEK THRU 7.5-MILE DITCH TO WILLOW CREEK, WHERE IT JOINED B.W. LAW'S DITCH, THEN ACROSS TO FOURMILE CREEK, DOWN ITS STREAM BED FOR 3 MILES, THEN BY PIPE FOR OVER 5 MILES ACROSS MUD SPRING GULCH, THEN BY DITCH ANOTHER 7 MILES TO COMPANY'S PROPERTY. GOOLDY USED WASTEWATER FROM TMDC PROPERTY UPSTREAM FOR GROUND SLUICING AT GOOLDY PLACER.

Comment (Deposit): FARNSWORTH'S ORIGINAL DESCRIPTION STATED THAT THE HIGHER PAYING ZONES IN AREA LIE IN SLIGHTLY CONSOLIDATED GRAVELS BENEATH IRON OXIDE-CEMENTED CONGLOMERATE AND ABOVE LAYER OF "BLUE CLAY," (NOW INTERPRETED AS EOCENE BEDROCK). AU CONCENTRATIONS IN TERRACE AND MANTLE DEPOSITS APPEAR LIMITED TO LEVEL BELOW THE PROMINENT CONGLOMERATE OR "CAP ROCK," WHICH WAS INTERPRETED BY PARKER (1974) AND THEOBALD AS A DELTAIC FAN IN EITHER THE TIPTON TONGUE OF GREEN RIVER FM (EOCENE) OR CATHEDRAL BLUFFS MEMBER OF WASATCH FM (EOCENE). MODERN PLACERS THUS WERE DERIVED FROM EOCENE FOSSIL BEACH AND ALLUVIAL PLACERS AND PROBABLY BEGAN FORMING IN LATE PLIOCENE OR PLEISTOCENE TIME. AGE OF MINERALIZATION CITED FOR DEPOSIT DEPENDS ON UNIT WORKED--EOCENE FOR BEDROCK OPERATIONS OR QUATERNARY FOR TERRACE, STREAM BED, AND MANTLE OPERATIONS. PARKER STATED THAT THIS DEPOSIT APPARENTLY WAS A SILTY ALLUVIAL TERRACE DEPOSIT 20 TO 25 FT ABOVE EAST TIMBERLAKE CREEK, BUT THAT THE SLOPE OF THE SURFACE OF THE DEPOSIT

Comment (Deposit): SUGGESTED A FAN OF (ANCESTRAL?) HOUSEL GULCH ORIGIN. ON AIRPHOTOS, PLACER CUTS HIGHER IN THE TRIBUTARY GULCHES APPEAR TO BE EITHER IN LOCALLY DERIVED ALLUVIUM FROM THE EAST-WEST TIMBERLAKE CREEKS INTERFLUVE

Comment (Workings): SURFACE WORKINGS IN APPARENT TERRACE ALONG EAST TIMBERLAKE CR. CUTS IN STREAM BED AND ADJACENT GROUND (APPARENT BEDROCK) ALONG TWO TRIBUTARY GULCHES
