|Location and accuracy||The occurrence is at an elevation of about 600 feet on the northwest side of Harriman Fiord, near the toe of Harriman Glacier. It is in the SE1/4 section 6, T. 10 N., R. 6 E., of the Seward Meridian. This is location 122 of Condon and Cass (1958), location 65 of Cobb and Richter (1972), location 79 of MacKevett and Holloway (1977), location 124 of Cobb and Tysdal (1980), and location S-154 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe occurrence consists of a 2- to 5-foot-wide quartz vein containing fault gouge. It is hosted in Valdez Group conglomerate and slate of Late Cretaceous age (Cobb and Tysdal, 1980). The vein strikes northwest and dips vertically and is traceable for 450 to 500 feet along strike. When crushed, the vein is said to pan gold (Johnson, 1914 [B 592-G, p. 229]). No other information is available.

|Mineral deposit model||Low-sulfide Au-quartz vein (Cox and Singer, 1986; model 36a)|
|Mineral deposit model number||36a|
|Age of mineralization||Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age.|
|Workings or exploration||
There are no workings or assay results reported for this occurrence. Johnson (1914 [B 592-G, p. 229]) reports that the crushed ore pans free gold.The U.S. Bureau of Mines searched for this occurrence in 1981 but did not locate it (Hoekzema and Sherman, 1983). They examined similar veins about 1.5 miles to the southwest. No samples were collected.
