Relative position | Sophie Gulch is a small east tributary to Rock Creek that enters Rock Creek at an elevation of about 230 feet and about 0.85 mile northeast of the Rock Creek crossing of the Snake River road. Sophie Gulch was included in localities 43 and 98 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The location shown as Sophie Gulch by Hummel (1962 [MF 247, location 17]) is the same as the Walsh Cut (NM214) of this report. The Sophie Gulch deposit was covered by U.S. Mineral Survey No. 721 (No. 1 Sophie Gulch Placer). The map location is just inside the north-central border of section 23, T. 10 S., R. 34 W., Kateel River Meridian and it is accurate to within 500 feet. |
