Location and accuracy Davis Creek is a small headwater tributary of the Walker Fork of the Fortymile River. Davis Creek is about 3 miles long; the upper 1 mile is located in Yukon Territory, Canada. Placer workings extend about 1.5 miles upstream from the mouth of Davis Creek; the coordinates are the approximate midpoint of the placer workings, in section 2, T. 26 N., R. 22 E., of the Copper River Meridian. The location is accurate. Davis Creek is localities 15 and 76 of Cobb (1972 [MF-393]), localities 20 and 37 of Eberlein and others (1977), and locality 109 of Burleigh and Lear (1994).

Geologic setting

Geologic description

Bedrock along Davis Creek consists of greenschist-facies carbonaceous schist and quartzite with abundant quartz lenses, as well as minor biotite-quartz schist (R.L. Flynn, unpublished data, 2000). These rocks are part of the Nasina Series of McConnell (1905) and are derived from a Mississippian protolith (Mortensen, 1999).
Near the mouth of the creek, the Davis Creek gravel consists of 4 feet of muck, overlying 4 feet of coarse gravel (with many boulders more than 8 inches in diameter), which in turn overlies 4 feet of finer gravel, pebbles, and sand that coarsen at the bottom (Spurr, 1898). The lower 4 feet of gravel was the pay streak; in many places gold also occurs in the top 6 to 8 inches of weathered bedrock. On the Discovery claim, located about one-half mile upstream of its mouth, the pay streak was 10 feet wide. Upstream, near the Canadian border, the gravel shallowed to just over 6 feet thick, and the pay streak at the base was reduced to 2 feet thick and less than 5 feet wide (Spurr, 1898). Gold in Davis Creek was coarse, and both rounded and flattened nuggets were recovered (Spurr, 1898). Placer gold from Davis Creek has a fineness of 885 parts gold per thousand (Metz and Hawkins, 1981).
Walker Fork (EA156) has produced placer gold downstream of Davis Creek; Poker Creek (EA158) and Younger Creek (EA159) are other nearby creeks with placer gold production. Although a significant lode source has not been identified for the gold in Davis Creek, Spurr (1898) described a horizontal quartz vein in schist that contained gold (see Lowry's Ledge, EA157).
Placer gold was first discovered in the Walker Fork drainage on Davis Creek in 1888; this discovery resulted in a stampede from Franklin Gulch (EA116) (Spurr, 1898). Thirty-five miners produced $30,000 of gold (gold at $20.67 per ounce) on Davis Creek in 1893 (Spurr, 1898). Davis Creek and the other headwater tributaries of Walker Fork were mostly mined out by the turn of the century, although there are several reports of mining on Davis Creek into the 1930s (Yeend, 1996). Mining was reported on Davis Creek in 1989 (Bundtzen and others, 1990). Yeend (1996) reports a small open-cut mining operation active in the early 1990s on Davis Creek. A small open-cut mining operation was active on Davis Creek from 1979 through 2000 (Norm LaFramboise, Boundary Explorations, Inc., written communication, 2000).
