Location: Tin Creek, within the Bering Land Bridge National Preserve, drains the lower elevations of the north flank of Ear Mountain. Ear Mountain is an isolated upland reaching a maximum elevation of 2,329 feet in the north-central Teller D-3 quadrangle. This locality is at 525 feet elevation in the headwaters of Tin Creek, 0.9 miles northwest of the Ear Mountain landing strip. This is locality 53 of Cobb and Sainsbury (1972) and Cobb (1975) summarized relevant references under the name 'Tin Cr., trib. Shishmaref Inlet'.
Geology: The Ear Mountain upland is cored by a Late Cretaceous (76.7 +/- 2.8 my) composite biotite granite stock (Sainsbury, 1972; Hudson and Arth, 1983). Country rocks to this stock are an impure and schistose carbonate sequence of unknown but probable Paleozoic age. Tin Creek does not have headwaters that cross the contact zone of the Ear Mountain granite stock directly although tundra-mantled slopes above the headwater area continue upward for 1.5 miles south to an area of significant lode tin metallization (Ear Mountain prospect, TE060)). A USBM churn-drill hole at this locality encountered 3 feet of overburden and three feet of gravel. The gravel contained a trace of tin per cubic yard and identified minerals included calcite, quartz, diopside, actinolite, tourmaline, orthoclase, albite, limonite (pseudomorph after pyrite), and cassiterite (Mulligan, 1959, p, 30).
Workings: One USBM churn-drill hole was completed here (Mulligan, 1959).
