Location and accuracy | Placer claims on Albert and Crooked Creeks extend for about six miles from the E1/2 sec. 12, T. 22 N., R. 11 E., to the SW1/4 sec. 23, T. 23 N., R. 12 E., Seward Meridian. This mine is on Albert Creek, in the SW1/4 sec. 8, T. 22 N., R. 12 E., Seward Meridian. The location is accurate to within 1/2 mile. |
Geologic descriptionThe rocks in the Albert Creek-Crooked Creek area are volcanic and sedimentary rocks of the Lower Jurassic, Talkeetna Formation (Csejtey and others, 1978). Gold occurs in stream gravels and low benches (Nokleberg and others, 1987). Fine gold also occurs in glacial and glaciofluvial deposits. Much of the gold is within 3 feet of bedrock and on the bedrock surface. Scheelite and platinum have been reported in some samples (Nokleberg and others, 1987). The gold is probably derived from gold-quartz veins in metagraywacke and phyllite of the Upper Cretaceous Valdez Group. Several placer claims are on Albert Creek (a tributary of Crooked Creek) and on Crooked Creek. Gold was discovered on Albert Creek in 1912, resulting in a small stampede; no other valuable deposits were found, but activity on Albert Creek continued to at least 1961 (Cobb, 1973 [B 1374]). One or more claims on Albert Creek produced 150 ounces of gold in 1914 (Chapin, 1918). | |
