|Location and accuracy||Southeast of village of False Pass on the Alaska Peninsula side of Isanotski Strait, just south of Nichol Point. Latitude and longitude are accurate; however, vein system is at least 1 km wide across strike and extends south of location given here.|
Geologic descriptionWell-developed, vertically oriented reticulated quartz vein system cutting mildly altered volcanic flows, rubble, breccia, and tuffaceous breccia. Zone extends more than 1 km across strike, veins are concentrated at northern end of zone. Sulfides are generally not apparent, though some areas have structures (vugs) indicating the removal of pyrite by weathering.
