|Location and accuracy||This prospect (or small mine) is north of the divide at the head of Limestone Creek. It is on an unnamed creek that flows northeast into the east lobe of the Chistochina Glacier. The prospect is in the N1/2NW1/4 section 28, T. 20 S., R. 16 E., Fairbanks Meridian. The placer corresponds to locality 26 on figure 6 of Cobb (1979 [OFR 79-238]), locality 77 of MacKevett and Holloway (1977), and locality 12 in table 3 of Nokleberg and others (1991). The location of the prospect or small mine described by Nokleberg and others (1991) as their locality 12 does not match the location shown by Cobb, and there is insufficient information to resolve the location issue.|
Rocks north of the Limestone Creek divide probably include limestone of Late Triassic age and the Nikolai Greenstone, also of Late Triassic age.According to Nokleberg and others (1991), the area of this placer prospect or small mine resulted from drainage of a Tertiary conglomerate probably similar to the 'round wash' of Miller Gulch (MH296).
