Location: The Deadwood Creek placer mine is about a half-mile upstream from the junction of North Fork. The site is at Deadwood claim number 1, where work was performed in 1980 (Alaska Kardex files). It is in the northeast quarter of section 1, T. 4 N., R. 13 W., of the Fairbanks Meridian. Three claims extend upstream from this site. The location is accurate within about 500 feet. This site closely corresponds with the site for Deadwood, U.S. Bureau of Land Management MAS number 0020480113.
Geology: The Deadwood Creek area is underlain by Cretaceous sandstone, siltstone, quartzite, and shale, and by Cretaceous or Jurassic quartzite (Chapman and others, 1982; Reifenstuhl and others, 1998). Deadwood Creek follows the trace of a thrust fault between the Cretaceous and Cretaceous or Jurassic units (Reifenstuhl and others, 1998). No igneous rocks are mapped nearby. Placer mining in the upper Pioneer Creek-Deadwood Creek area began in 1902 (Collier, 1903). Most of the gold reportedly was mined from benches on the northwest side of Pioneer Creek or from secondary reconcentrations on the tributaries that cut across those benches (Mertie, 1934). Early work specifically on Deadwood Creek is not recorded. Placer mining claims were staked along Deadwood Creek in 1977 (Alaska Kardex files), and the claims were worked from 1977 to at least 1985. Affidavits of annual labor list digging holes up to 14 feet deep with a backhoe, and backpack drilling to 35-foot depth in 1979; sluicing ground on claim number 1 in 1980; stripping overburden and digging test holes with a backhoe in 1983 in preparation for mining the following year; stripping and ripping topsoil and frozen overburden with a D-8 Caterpillar bulldozer in 1984; and digging bedrock drains in 1984 and 1985.
