Geographic coordinates

Geographic coordinates: -149.38333, 67.59971 (WGS84)
Relative position This site is at an elevation of about 3,500 feet approximately 6 miles north-northeast of the north end of Bob Johnson Lake (formerly Big Lake) and 1/2 mile east of the head of Limestone Creek, a south-flowing tributary to the Bettles River (sec. 17, T. 32 N., R. 8 W., of the Fairbanks Meridian). The reference point for this site is the same as that for loc. 37 in DeYoung (1978). The location is accurate within a 1/2-mile radius.

Comments on the geologic information

  • Geologic Description = Nickel, palladium, and silver were reported in an X-ray analysis of rock from a thrust sheet of Skajit Limestone (Brosgi and Reiser, 1964). The occurrence is in a section of Skajit Limestone that has overridden Devonian(?) quartz muscovite schist along a major northeast-trending thrust fault. A later examination of the occurrence (Foley and others, 1989) found no evidence of anomalous nickel, palladium, and silver. Heiner and Wolff (1968) described Limestone Creek as a placer gold occurrence on which one claim was located in 1954, but inactive since then. There are no other reports or any evidence to substantiate that this site was a placer gold occurrence.
