Location: The location of the reference point is speculative because the location of the occurrence is described only as being on a right-limit tributary of Phoebe Creek. The reference point is near a cabin shown on the topographic map on a large right-limit tributary of Phoebe Creek opposite the mouth of Mellow Creek (NE1/4 sec. 29, T. 32 N., R. 7 W., of the Fairbanks Meridian). The location is accurate within a 1-mile radius.
Geology: Reed (1938) reported that there is no record of prospecting on Phoebe Creek itself but that very good prospects were found on a right-limit tributary by Manual Mello in the early days 1900s. No other information is available on this occurrence. The occurrence is in an area underlain by Ordovician to Cambrian(?) feldspar-quartz schist, which has been intruded by biotite granite gneiss and aplite phases of the Devonian Baby Creek batholith (Dillon and others, 1996). Calcareous and siliceous hornfels have been developed near the intrusive contacts, and this entire assemblage is in thrust contact with Lower Paleozoic to Proterozoic units that are predominantly banded quartzite and graphitic schist.
Age: Quaternary.
