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
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
