|Location and accuracy||Location of placer claims includes the length of Bird Creek, located on the north side of Turnagain Arm. Lode claims located upstream. Locality 68 of MacKevett and Holloway (1977).|
Geologic descriptionPlacer claims in stream draining Late Cretaceous Valdez Group metasedimentary rocks. Gold found in stream deposits sporadically; an aplite sample from a lode claim in 1898 assayed 0.36 oz/ton Au (Mendenhall, 1900).
|Geologic map unit||(-149.412189603949, 61.0194510760047)|
|Mineral deposit model||Placer Au (Cox and Singer, 1986; model 39a)|
|Mineral deposit model number||39a|
|Age of mineralization||Quaternary.|
|Workings or exploration||Placer claims worked for several years between 1898 and most recently in 1938. Most claims proved to be disappointing. In 1915, a tunnel was driven 144 ft in slate to tap an old channel about 8 miles above Bird Creek mouth. Prospector was not successful (Capps, 1916). An aplite sample from a lode claim in 1898 assayed 0.36 oz/ton Au (Mendenhall, 1900).|
|Indication of production||Yes; small|
