|Location and accuracy||This placer prospect is somewhat arbitrarily located on Athell Creek at the boundary between the Gulkana and Nabesna quadrangles. This location was chosen because of several conflicting locations. Richter (1966, fig. 5) shows one placer prospect on the Nabesna D-6 quadrangle about one-mile downstream from the quadrangle boundary. Richter and Matson (location 21, 1972) give a locality on Ahtell Creek about 0.8 miles upstream from the quadrangle boundary. In 1938, Moffit (1938, p. 51) reported that in 1936, prospecting for placer gold was in progress 'near the lower end of the canyon, 2 miles from the Slana Bridge. Ahtell Creek was also reported as auriferous by MacKevett and Holloway (1977, locality 20) in the SE1/4NE1/4, section 13 T. 11 N., R. 7 E., Copper River Meridian.|
Ahtell Creek drains a large region known to be locally auriferous. Grubstake Creek (GU017) the most productive gold placer in the region enters Ahtell Creek about 4 miles above this site. A lode gold prospect, the Gold-Quartz prospect, (GU013), is in the Ahtell Creek canyon just above this site.A description of prospecting activities on Ahtell Creek in 1936 by Moffit (1938, p. 51) suggests that the Ahtell Creek placer is of river-bar type, formed by the reworking of low-grade materials. Moffit reported that the prospect was in the canyon of Ahtell Creek where auriferous gravel deposits of probable local derivation formed in the bends of the river and at its mouth.
