Preliminary report on stratigraphy and structure of the area of the Colville River between Ninuluk and Prince Creeks, Alaska

Geological Survey Party 4 began studies at a point on the Colville River 18 miles downstream from the mouth of the Killik River on July 19. From this point the studies were continued along the Colville River to near the mouth of Prince Creek. The investigation was completed on September 1 and the party returned to Umiat. A traverse was made along the lower half of Prince Creek and along one of its northern tributaries between September 8 and September 15. Canvas boats were used for transportation along the Colville River and a weasel was used to traverse Prince Creek. The party was composed of four members: R. L. Detterman and D. E. Mathewson, geologists; J. L. Townley, surveyor; and Charles Segal, cook.
