Identification information

Deposit ID 10003233
MRDS ID A016050
Record type Site
Current site name Unnamed (on Rapid River)

Geographic coordinates

Geographic coordinates: -167.18229, 65.40815 (WGS84)
Relative position This is the localtion of two USBM churn-drill holes on the lower part of Rapid River. Rapid River is the major west tributary of Lost River. Its mouth is located one mile upstream from the mouth of Lost River on the Bering Sea. The two churn-drill holes are 0.4 and 0.75 miles upstream from the mouth of Rapid River. This is locality 45 of Cobb and Sainsbury (1972). Cobb (1975) summarized this reference under the name 'Rapid R.'.

Comments on the geologic information

  • Geologic Description = Bedrock in the 7-mile long southeast flowing Rapid River and its tributary drainages includes various Ordovician limestone facies and local mafic and felsic dikes (Sainsbury, 1969). The two USBM churn-drill holes in the lower part of the river encountered relatively thick gravels for the area; 23 feet of gravel over limestone bedrock in one and more than 30.5 feet of gravel in the other (bedrock was not encountered). Heavy mineral concentrates from both churn-drill holes indicate a trace of tin in the gravels (Mulligan, 1959, p. 13). The mineralogy of the concentrates was not determined. Mulligan (1959, 12-13) notes that the gravel thickness decreases to only a few feet a short distance upstream from the drill holes.
