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. DEPOSITS HERE PROBABLY WORKED IN BIGHOLE GULCH STREAM BED AND TERRACE AND FLOOD-PLAIN ALLUVIUM NEAR MOUTH OF BIGHOLE GULCH AT CONFLUENCE WITH LITTLE SNAKE RIVER.
