Relative position | The Rock Creek lode prospect is best developed for a strike distance of about 1,000 feet in the Rock Creek valley above the confluence of Rock Creek and Sophie Gulch (NM208). The map location is the approximate midpoint of the deposit, about 1.4 miles southwest of Mount Brynetson. Surface elevations at the prospect range from 230 to 270 feet. The location is just inside the south-central border of section 14, T. 10 S., R. 34 W., Kateel River Meridian, and it is accurate to within 500 feet. It is included in locality 43 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The prospect includes a claim or site called Nugent by Mertie (1918 -- A012834). |
