Location: Iron Creek is a small, west-flowing tributary to Eldorado Creek. There is some uncertainty about which tributary of Eldorado Creek is Iron Creek. Harrington (1919) shows Iron Creek as entering Eldorado Creek a considerable distance from the mouth of Eldorado Creek. A local prospector (Doug Clark, oral commun., 2001) confirms this and claims that Iron Creek is the eastern headwater tributary of Eldorado Creek. The junction of this tributary and Eldorado Creek is approximately three miles from the mouth of Eldorado Creek. Iron Creek is locality 3 of Cobb (1972 [MF 367]); his location is at least two miles south of the mouth of Eldorado Creek and two miles east of Eldorado Creek. The current (1954/1965) U.S. Geological Survey Ophir B-2 topographic map shows Iron Creek near the mouth of Eldorado Creek. For this record, the coordinates are at the approximate midpoint of Iron Creek as described by Harrington (1919) and Clark, in sec. 13, T. 24 S., R. 10 E., Kateel River Meridian. The location is accurate within 5 miles.
Geology: Bedrock in the vicinity of Iron Creek consists of volcanic rocks; a monzonite intrusion underlies its headwaters (Chapman and others, 1985; S. Dashevsky, unpublished data, 2000). Gravel in Iron Creek consists of phyllitic rocks and granite, overlain by four feet of muck (Harrington, 1919). There was some placer mining in Iron Creek by 1917 (Harrington, 1919). Small-scale prospecting has occurred since that then. Also see OP007-009.
Workings: Gold mining along Iron Creek was underway by 1917 (Harrington, 1919). Small-scale prospecting has occurred since then.
Age: Quaternary. The source of the placer gold is probably a Cretaceous or Tertiary monzonite intrusion in the headwaters of Iron Creek (Bundtzen and others, 1987).
