|Location and accuracy||The Doherty prospect is at an elevation of about 2950 feet on the southeast flank of Wickersham Dome above Eureka Creek. It is in the NE1/4 of section 7, T. 16 S., R. 17 W., Fairbanks Meridian. The location is approximately at the discovery pit shown on the plat of the Doherty patented claim; the pit is about 300 feet from the southwest end line of the claim (Hawley and Associates, 1978).|
Geologic descriptionThe Doherty claim is in a NNW-trending fault block near the axis of the Kantishna antiform (see MM091). In general, rocks near the axis of the antiform belong to the Spruce Creek sequence, but in the Doherty block these rocks have been displaced to the south and the country rocks at the claim belong to the Birch Creek Schist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2). Little is known about the deposit. Two prospect pits aligned along the northeast-trending lode line of the claim suggest a vein that strikes NE, but there has been no detailed mapping to substantiate this. The claim is northeast of and partly overlaps the Pittsburgh claim (MM109). The Doherty claim probably was located as a gold prospect.

|Workings or exploration||The claim was prospected by shallow pits; a discovery must have been present to qualify the claim for patent.|
|Indication of production||None|
Additional commentsThe prospect is in Denali National Park and Preserve.
