|Location and accuracy||Tip Creek is a 12-mile-long, east-flowing tributary of the Sulatna River. The prospect is near the head of the creek, but its location is not precisely known. The coordinates for Tip Creek correspond to location 53 of Eberlein and others (1977) and are arbitrarily placed on the creek in section 7, T. 12 S., R. 19 E. of the Kateel River meridian. The location is accurate within 5 miles.|
The Tip Creek valley is broad and flat, and the alluvium is deep (Eakin, 1914). Cass (1959) mapped the headwaters as draining a unit containing schist, crystalline limestone, quartzite, greenstone, slate and phyllite. To the south several miles Cass also mapped greenstones. The relationship of these rocks (or any others) is unknown based on the deep alluvium.According to Eakin (1914 [B578]), prospects worthy of further examination were found in the upper reaches of Tip Creek in or before 1912. However, no mention of Tip Creek occurs again until Mertie (1936) reported that prospecting has, in the past, occurred there. Eberlein and others (1977) concluded that the area is poorly explored due to the ground being covered by 80 feet of alluvium. There is no evidence that any mining took place at Tip Creek.
