|Location and accuracy||Albion Creek is a small west tributary to Crooked Creek; its mouth is about 6,000 feet upstream of the confluence of Crooked Creek (BN102) and Ophir Creek (BN099). Crooked Creek is a short, 2.3 mile long west tributary to Ophir Creek. The mouth of Crooked Creek is 7,500 feet upstream on Ophir Creek from the southern boundary of the Bendeleben quadrangle. This is locality 81 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionPlacer gold mining, including dredging, has taken place along at least the lower 2,000 feet of Albion Creek as well as on the slope along the north bank up to 100 feet in elevation above the creek. The placer deposit above the creek was called a hillside placer (Smith, 1908) but it is not known if this was residual in character. Gravels in the creek are reported to be locally derived and auriferous throughout its length (Collier and others, 1908; Smith and Eakin, 1911). A section near its mouth included 3 feet of locally derived gravel covered by 3 feet of overburden. Bedrock in the area is metasedimentary schist and marble of a lower Paleozoic assemblage (Till and others, 1986). Two occurrences of gold in bedrock (BN104 and BN125) are known near the headwaters of Albion Creek.
