|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 2.75 miles upstream from the mouth of the creek and in proximity to the mouths of its tributaries, Eureka and Boulder Creeks. It is locality 31 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Baituk Cr.'.|
Geologic descriptionBedrock in the 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 5.5 feet of gravel over bedrock. Heavy mineral concentrates from these drill holes contained a trace of tin in one and 0.02 pounds of tin per cubic yard in the other; one contained detectable gold. The heavy minerals included pyrite, limonite psuedomorphs after pyrite, augite, magnetite, ilmenite, apatite, zircon, tourmaline, cassiterite and gold. Two prospect pits, neither of which reached bedrock, did not contain detectable tin, eU, or gold.
