|Location and accuracy||Arizona Creek is a west tributary to Kougarok River. The mouth of Arizona Creek is 4.5 miles south of Taylor and 1.7 miles west of the Nome-Taylor road. Sainsbury and others (1969) show 1,500 feet of placer mine workings on the main channel starting 1,500 feet upstream of the mouth. This is locality 32 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionSainsbury and others (1969) show 1,500 feet of placer mine workings on the main channel of Arizona Creek starting 1,500 feet upstream of the mouth. Much of the early placer mining here was on bench gravels at elevations of 20 to 70 feet above the floodplain (Collier and others, 1908; Smith, 1909). The bench placers are probably in gravels related to locally preserved Kougarok River terraces.
|Geologic map unit||(-164.78868778955, 65.6102727828664)|
|Mineral deposit model||Placer Au-PGE (Cox and Singer, 1986; model 39a)|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary; placers on present floodplains are probably the result of at least two cycles of erosion and placer development.|
|Workings or exploration||Surface open-cut placer workings, at least 1,500 feet, are on the main channel of Arizona Creek starting 1,500 feet upstream of the mouth. Much of the early placer mining here was on bench gravels at elevations of 20 to 70 feet above the floodplain (Collier and others, 1908; Smith, 1909).|
