Location and accuracy The prospect is at the head of Rocky Mountain Creek, an east tributary to upper Nome River, at an elevation of about 1,000 feet. The prospect is locality 34 of Hummel (1962 [MF 248]) and is located within about 1,000 feet of the coordinates.

Geologic setting

Geologic description

Hummel (1962 [MF 248]) identified this locality as an iron sulfide occurrence and part of a group of prospects that contained pyrite, arsenopyrite, and at some of the prospects, pyrrhotite. The sulfides may be disseminated or in veins. The prospect is near or at the upper contact of calcareous schist with a marble layer; the rocks strike northwest and dip northeast (Hummel, 1962 [MF 248]).
