Geologic setting

Geologic description

Prospects along Iron Creek were first reported by Brooks in 1907. The pay streak was reported to be irregular and spotty, with coarse gold of high grade. One sample assayed $18.75 an ounce (1930 dollars) (Mertie, 1930). The bedrock at the head of Iron Creek is composed of Cretaceous to Tertiary sedimentary rocks and Upper Devonian (?) conglomerate. In the lower part of the drainage the conglomerate contains pebble- to boulder-size clasts of quartzite and chert (Dover and Miyaoka, 1988).
Iron Creek was first staked in 1901, and almost all early work was done by drift mining. In 1926, production was reported to be 9 troy ounces of gold and 1 troy ounce of silver. Iron Creek may still be a site of active mining and prospecting (National Park Service, 1990).
