Geol., p. 79, Aug., 1932, and GSA Bull., p. 167-168, Feb. 28, 1933


Summary:

Is well exposed at Yakataga Reef and on north and south flanks of Yakataga anticline, Controller Bay-Yakataga region, southern AK. Consists of series of sandstones, dark shales, and conglomerates. Thickness is in excess of 5000 ft. Partial measured section of unit at Yakataga Reef is 1538 ft thick. Conformably overlies Poul Creek formation (new). Fauna obtained from both Poul Creek and Yakataga formations are of late Oligocene age according to B.L. Clark.

Summary:

Yakataga formation of Taliaferro (1932) [adopted]. Lower part of Yakataga Reef section is reassigned to Poul Creek formation. Yakataga in southeastern part of Robinson Mountain is at least 10,000 ft and possibly 15,000 ft thick. Stratigraphic section included in report. There is diversity of opinion regarding age. F.S. MacNeil regards age as middle and late Miocene and possibly early Pliocene.
