Location and accuracy This occurrence is on the southwest side of Straightaway Glacier near its terminal moraine. It probably is in the E1/2 sec. 25, T. 20 S., R. 21 W., Fairbanks Meridian. The location was reported in claim records compiled by the U. S. Bureau of Mines (1973). The locality is number 62 of MacKevett and Holloway (1977). The location is probably accurate within a radius of 1 mile.

Geologic setting

Geologic description

The country rocks near the terminus of Straightaway Glacier are probably rhyolite, conglomerate and other units that Reed (1961) proposed were interstratified with the Cretaceous or Tertiary Cantwell Formation. The rhyolite is probably Tertiary. Nothing is known of the geologic nature of this mineral occurrence, whose existence is inferred from a gold claim at this site (U.S. Bureau of Mines, 1973).
