Geologic information

Identification information

Deposit ID 10307253
Record type Site
Current site name Kisaralik River (Riglagalik River)

Geographic coordinates

Geographic coordinates: -159.60277, 60.39932 (WGS84)
Relative position This occurrence is assumed to be on the upper Kisaralik River, formerly called the Riglagalik River. Hoare and Cobb (1977), under the name 'Riglagalik R.', included an early report of a gold and possibly cassiterite occurrence on this river but a specific location was not available. For this record, the map site is in the SW1/4 of section 12, T 3 N, R 60 W, of the Seward Meridian.

Comments on the geologic information

  • Geologic Description = The Kisaralik River is a large drainage that heads in the eastern part of the Bethel quadrangle. Fine gold (Brooks, 1912, p. 41) and cassiterite in heavy mineral concentrates (Martin, 1919, p. 43) have been reported at unkown locations on the Rigagalik River, an early name for the Kisaralik River (Hoare and Cobb, 1977, p. 21). Whereas placer gold is likely to have been found along many parts of Kisaralik River, such as at Golden Gate Falls (BH005), the presence of cassiterite has not been verified. For this record, the location of these reported occurrences is arbitrarily placed in the upper part of the river.
  • Age = Quaternary.
