Location: Deer Creek is a short, 2-mile long north tributary to Crosby Creek with headwaters on the south flank of Ear Mountain. Ear Mountain is an isolated upland reaching 2,329 feet elevation in the north-central Teller D-3 quadrangle. It is cored by a Late Cretaceous granite stock (Sainsbury, 1972). Quartz Creek has headwaters in the contact zone of the granite but it does not extend northward into the stock itself. This is locality 56 of Cobb and Sainsbury (1972). Cobb (1975) summarized references for this locality under the name 'Deer Cr., trib. Crosby Cr.'.
Geology: Deer Creek has headwaters in the contact zone of the Ear Mountain granite stock (Sainsbury, 1972). This is a Late Cretaceous (76.7 +/- 2.9 my; Hudson and Arth, 1983, p. 769) composite biotite granite that intrudes an impure and schistose carbonate sequence, with some metapelitic rocks, of unknown but probable Paleozoic age. The USBM completed one churn-drill hole at about 350 feet elevation on this creek (Mulligan, 1959, p. 20). The lower part of the 6 feet of gravel and the adjacent bedrock here contained 0.02 pounds of tin per cubic yard. Minerals identified in the churn-drill sample include quartz, orthoclase, oligoclase, pyrite, limonite pseudomorphs after pyrite, and small amounts of grossularite garnet, tourmaline, idocrase, chondrodite, epidote, and actinolite. Cassiterite was identified (Mulligan, 1959, p. 29).
Workings: One USBM churn-drill hole has been completed on the creek (Mulligan, 1959, p. 20).
