|Location and accuracy||The location is the approximate position of claims on Ptarmigan Creek. Ptarmigan Creek is a tributary of the Chatanika River and is accessible where the creek crosses the Steese Highway. (This should not be confused with the other Ptarmigan Creek that is a tributary of Birch Creek, Circle quadrangle B-4).|
Geologic descriptionThere is little gravel, but good colors can be panned from the lower part of the creek (Menzie and others, 1983, p. 51). A trace-element study showed 28 percent Ag in a sample of placer gold from Ptarmigan Creek (Yeend, 1985, p. 6).

Additional commentsThe Ptarmigan Creek discussed for this record is a tributary of the Chatanika River. Another Ptarmigan Creek is located further up the Steese Highway and is a tributary of Birch Creek (see Ptarmigan Creek, tributary of Birch Creek, ARDF no. CI048).
