Relative position Lost River is the major south-flowing drainage in the York Mountains of western Seward Peninsula. This locality is on the main drainage, just below the mouth of Cassiterite Creek, 5 miles upstream from the mouth of Lost River on the Bering Sea. This is locality 43 of Cobb and Sainsbury (1972). It was not included separately by Cobb (1975).

Comments on the geologic information

  • Geologic Description = Bedrock in this drainage and its tributaries are various Ordovician limestone facies locally intruded by felsic and mafic dikes and granite stocks (Sainsbury, 1969). The USBM completed three churn-drill holes in a line across Lost River at his locality. These holes encountered 5 to 9 feet of gravel over limestone bedrock. Gravel from lower parts of these holes contained 0.04 and 0.05 pounds of tin per cubic yard (Mulligan, 1959, p. 13). The heavy minerals in these gravels were not identified.
  • Age = Quaternary
