Deposit WORKINGS CONFINED TO MOUTH OF DISAPPOINTMENT CREEK, WITH MAXIMUM WIDTH OF 300 FT.. GRAVELS CONTAINING GOLD IN ECONOMIC QUANTITIES WERE IRREGULARLY DISTRIBUTED. DEPOSITS NOT OVER 10-12 FT. DEEP TO BEDROCK, EXCEPT AT MOUTH OF CREEK, WHERE HOLES SUNK 35 FT. DEEP FAILED TO REACH BEDROCK. UPPER PORTION COMPOSED OF 2-3 FT. OF SOIL AND VEGETABLE MATTER. LOWER STRATUM OF GRAVEL CONTAINS GOLD. GRAVELS MOSTLY SMALL AND WELL-ROUNDED PEBBLES UP TO 8 IN. DIAMETER COBBLES.
Deposit STREAM GRADIENT 150 FT/MI.. ALTHOUGH GOLD WAS PRESENT, NO MINING WAS CONDUCTED ON WILSON CREEK GRAVELS BEYOND MOUTH OF DISAPPOINTMENT CREEK. ; INFO.SRC : 1 PUB LIT
