Comments on the geologic information

  • Geologic Description = Loper Creek flows north approximately 17 miles from its headwaters near Pinnel Mountain to its mouth at Preacher Creek. Good placer gold prospects were reported as early as 1908 in unfrozen gravel less than 8 ft deep (Brooks, 1909, p. 54). In the mid-1980's a rough road was bulldozed from the upper part of Porcupine Creek across the drainage divide and down into the upper part of Loper Creek. Some stripping of muck was done along the margins of Loper Creek, although it is not known if any mining was subsequently done (Yeend, 1991).
