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 4.25 miles upstream from the mouth of the creek. It is locality 30 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Baituk Cr.'.

Geologic setting

Geologic description

Bedrock 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 three USBM churn-drill hole completed at this location encountered 4 to 5 feet of gravel over bedrock. Heavy mineral concentrates from these drill holes contained a trace of tin and one contained a trace of gold. The heavy minerals included pyrite, limonite psuedomorphs after pyrite, augite, cassiterite and gold.
A sample from a prospect pit on Justice Creek contained 0.003 % eU and a trace of gold. Two other prospect pits in the area failed to reach bedrock and samples from them did not contain uranium or gold values.
