Comments on the geologic information

  • SCHIST IN HEADWATER SECTION OF CREEK EXPOSED BY RECENT EROSION OF OVERLYING GRAVELS. ; MAJOR.UNITS: BEDROCK FOR THE UPPER 1.5 MILES OF CREEK IS SCHIST; LOWER 3.5 MILES CUT IN NENANA GRAVEL. TRANSITION FROM SCHIST TO GRAVEL BEDROCK ABOUT 1/4-1/2 MILE ABOVE THE MOUTH OF WILSON CREEK. ; REG.COM: GOLD PROBABLY DERIVED FROM LIBERTY BELL AND SIMILAR LODES. THE FACT THAT NO NOTABLE CONCENTRATIONS OF PLACER GOLD HAVE BEEN FOUND DOWNSTREAM OF WILSON CR. CONFLUENCE, POINTS TO THE CONCLUSION THAT OLD GRAVELS CARRY VERY LITTLE IF ANY GOLD.
