Location and accuracy This prospect is on west valley wall of the small hanging glacier above the head of Pocket Creek, a west tributary to Monahan Creek. It is at an elevation of about 6,300 feet, 2,000 feet north of peak 7020. The site is near the northwest corner of section 1, T. 10 S., R. 11 E. of the Copper River Meridian. This is locality 10 of MacKevett (1976); the location is probably accurate to within 1,000 feet. Cobb and MacKevett (1980) included this prospect under the name 'Nelson'.

Geologic setting

Geologic description

At this prospect, five gold-bearing quartz veins to 16 inches thick cut Cretaceous Valdez Group metaflysch. The veins carry spotty gold values and are associated with three north-trending felsic dikes (Moffit, 1937). The deposits are on a steep slope but some trenches or prospecting pits are probably present. Gold-bearing quartz veins in the Valdez Group are generally Early Tertiary in age (Goldfarb and others, 1997).
