Comments on the geologic information

  • SOUTHWARD-DIPPING LAVA FLOWS, INTERCALATED WITH THICK BEDS OF CONGLOMERATE, FORM A RUGGED TERRAIN. THIS CONGLOMERATE, WHICH CONSISTS MAINLY OF COARSE, SUBANGULAR PEBBLES OF GNEISS AND GRANITE, RATHER FIRMLY CEMENTED IN A SANDY TO CLAYEY MATRIX, FORMS THE BEDROCK OF THE PLACERS. THE GOLD BEARING GRAVELS OCCUR PRINCIPALLY AS ANCIENT BARS SEVERAL FEET ABOVE THE STREAM CHANNEL AND, TO A LESS EXTENT, IN THE PRESENT STREAM BED. THE GOLD OCCURS AS PARTICLES UP TO 0.15 INCH IN DIAMETER, MOSTLY CONCENTRATED AT OR NEAR BEDROCK. IT APPEARS TO HAVE BEEN DERIVED BY EROSIN OF THE CONGLOMERATE, IN WHICH IT WAS PROBABLY PRESENT AS LOW-GRADE PLACER MATERIAL DERIVED FROM GOLD BEARING QUARTZ VEINS ORIGINALLY CONTAINED IN THE GNEISS, SCHIST, AND GRANITE OF THE RANGE
