Geologic setting

Geologic description

There is no record of mining on Limestone Creek (Kurtak and others, 2002). However, Reed (1938) reported that an 18-foot shaft was sunk near the mouth of the creek with indifferent results. Kurtak and others (2002) found remnants of a boom dam and cabin near the mouth of the creek that may indicate some unreported mining. They panned the creek at several locations for about 2 and a half miles above its mouth; none of their pans showed visible gold.
