The Polly Wonder claim is in Denali National Park and Preserve. It is sometimes included in the Dalton group of claims, which cover the Martha Q (MM121), and the contiguous Star and Friday claims (MM117) (Thornsberry, McKee, and Salisbury (1984, v. 2, location 29).
Location: The Polly Wonder prospect (Cobb, 1980 [OFR 80-363]) is on the north flank of Quigley Ridge at an elevation of about 2500 feet. It is about 0.1 mile northwest of the center of section 12, T. 16 S., R. 17 W. Fairbanks Meridian. The location is probably accurate within 300 feet. The site is near the discovery location of the patented Polly Wonder claim (Hawley and Associates, 1978). The claim is included with the Golden Eagle, Gold Dollar (MM110), and Little Annie (MM115) claims in location 9 of Cobb (1972 [MF 366]) and location 7 of MacKevett and Holloway (1977).
Geology: The country rocks in the area of the Polly Wonder claim are metafelsite schists of the Spruce Creek sequence (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2). The deposit consists of a vein that strikes about east and dips 65-70 south. The vein is about 7 feet thick and is composed mainly of iron-stained quartz with some galena; free gold can be panned on the outcrop (Davis, 1923, p. 125). A sample across the vein assayed 0.12 ounce of gold per ton and 2.2 ounces of silver per ton (Wells, 1933, p. 364).
Workings: In about 1920, the property was owned and prospected by Quigley and Dalton. In about 1960, the Polly Wonder and adjacent claims were mapped and soil sampled by Moneta-Porcupine (Seraphim, 1962).
Age: The deposit is assumed to be Eocene (see record MM091).
Alteration: Local iron staining.
