Location and accuracy A likely location for this prospect is near the southwest end of Lower Sweetheart Lake near the southeast corner of section 19, T. 45 S., R. 73 E. However, this prospect dates to before 1906 and has apparently not been located since; it may be a mile or so away from the location given here.

Geologic setting

Geologic description

Spencer (1904, 1906) reported a gold-quartz prospect with galena northwest of Lower Sweetheart Lake near its outlet. Three claims were staked on it in 1902 by Frank Cook. There is no additional information on the prospect and Kimble and others (1984) could not locate it. The rocks in the area are Cretaceous hornblende schist and biotite schist (Brew and Grybeck, 1984).
