Maddren (1913, p. 105) noted that Emery Creek was the only tributary of the Bettles River on which there has been any placer gold production.
Location: Emery Creek, a north-flowing tributary to the Bettles River, is approximately 2 miles northwest of Glacier Lake. Emery Creek, the name shown on the modern topographic map, is generally referred to as Emory Creek in the literature. The reference point for the Emery Creek placer is approximately 1 mile upstream from the Bettles River (SW1/4 sec. 32, T. 32 N., R. 9 W., of the Fairbanks Meridian) at about the midpoint of a 2-mile stretch of mining. The location is accurate within a 1/2-mile radius.
Geology: According Maddren (1913), Emory (sic) Creek had produced $10,000 in gold by 1909. The gold occurred on bedrock amidst boulders which had to be moved to recover the gold. Reed (1938) saw no evidence of the mining that Maddren had earlier reported, but he noted prospecting near the junction of Emory Creek with an east-flowing tributary. The results of this prospecting were unknown. Bedrock in the area is mapped as Ordovician black phyllite and intercalated marble (Dillon and Reifenstuhl, 1990).
Workings: Possible mining in the early 1900s and later prospecting.
Age: Quaternary.
Production: Production of approximately $10,000 (early 1900s gold price) from 1900 to 1909 (Maddren, 1913).
