The coordinates are near the midpoint of the creek at an elevation of about 3,750 feet, near the southeast corner of sec. 6, T. 22 N., R. 12 E., Seward Meridian. The location is accurate.

Geologic setting

Geologic description

The rocks in the drainage of North Creek drains are volcanic and sedimentary rocks of the Lower Jurassic, Talkeetna Formation (Csejtey and others, 1978). The gold placers occurs in Tertiary(?) alluvial gravel. Fine gold also occurs in Quaternary glacial and glaciofluvial deposits in the vicinity, but not in mineable quantities (Cobb, 1973 [B 1374]). Intermittent, small-scale mining occurred from 1912 to at least 1961 (Cobb, 1973).
