|Current site name||Nome Offshore Placer deposits|
|Geographic coordinates:||-165.50299, 64.49928 (WGS84)|
|Relative position||The Nome Offshore placer area extends from Present Beach offshore for 2 miles to water depths of about 60 feet. It extends about 10 miles parallel to the modern strandline, commencing west of the the mouth of Nome River and continuing westward to the vicinity of Penny River. The map location is the southwest corner of the C-1 quadrangle, which is offshore, and in a known gold-bearing area.|

|Deposit||Model Name = Placer; offshore, relict gravel, submerged beaches.|
|Deposit||Other Comments = High-resolution seismic surveys initiated by the U.S. Geological Survey (Tagg and Greene, 1973) and further refined by industry (Graul and others, 1989) were effective in mapping glacial deposits, possible covered beach deposits, and channels.|
