Comments on the location information

  • FONTAINE (1883, P. 190) DESCRIBES PROSPECT AS BEING HIGH UP ON PILOT (ABNERS) KNOB. THE KNOB IS NOW DESIGNATED CALFEE KNOB BY THE U.S.G.S. FIELD CHECKED. COULD NOT LOCATE PROSPECT IN 1988 (R.S. GOOD). NOTED DEPRESSION OR PIT ABOUT HALFWAY UP THE NORTHEAST SLOPE AND PITS ON THE EAST SIDE; CUT(?) IN ROME FORMATION ON THE NORTH SIDE OF CALFEE KNOB ON C.E. WILLIAMS PROPERTY.S
