Deposit GOLD IN BASAL FEW FEET OF GRAVEL AND IN TOP FOOT OF WEATHERED BEDROCK. BENCH NORTH OF CREEK IS CROSSED BY SMALL TRIBUTARIES IN POORLY DEFINED VALLEYS. IN MOST PLACES BEDROCK IS OVER 100 FT. DEEP. MINING IN 1931 WAS ON INNESVALE GULCH; 5-6 FT. OF GRAVEL BENEATH 90 FT. OF MUCK; GOLD IN LOWER 2 FT. OF GRAVEL AND UPPER FOOT OF BEDROCK. MOST OF DRIFT MINES APPEAR TO BE ON BENCH 1/4 MILE SOUTH OF CREEK.
