|Location and accuracy||Baituk Creek is a south-southwest flowing stream about 6 miles long, that enters the Bering Sea about 5.5 miles east of Tin City and 3.7 miles west of York. This location is one mile upstream from the mouth of the creek. It is locality 32 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Baituk Cr.'.|
Geologic descriptionBedrock in this drainage is a slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies (Sainsbury, 1972). The two USBM churn-drill holes completed at this location encountered 5 and 8.5 feet of gravel above bedrock. Heavy mineral concentrates from these drill holes contained a trace of tin and one contained detectable gold. The heavy minerals included pyrite, limonite psuedomorphs after pyrite, augite, magnetite, ilmenite, apatite, hornblende, and cassiterite.
