The present report presents the results of work done in part of the 1950 field season and supplements reports by Barnes (1949) and Cobb (1950) on coal investigations on the southern and southwest margins of the Homer district. Barnes' report covers investigations of coal-bearing rocks of the Kenai formation of Tertiary age in a coastal belt between Bluff Point, 1-1/2 miles west of Homer, and the head of Kachemak Bay. Cobb's report deals with similar rocks exposed along the shore between Bluff Point and Deep Creek. The present report covers an extension of this work from Deep Creek along the east shore of Cook Inlet to the most northerly exposures of rocks of the Kenai formation in the beach bluffs about 6 miles south of the mouth of the Kasilof River, Outcrops of coal-bearing rocks along the Storling Highway and the lower reaches of the Ninilchik River also were investigated. The writer, assisted by F.J. Markewicz, carried on the field work which is the basis for this report between June 1 and August 12, 1950. Field work comprised measurement of stratigraphic sections, tracing of coal beds, geologic mapping along the shorn of Cook Inlet, the lower part of the Ninilchik River, and the Sterling Highway, and sampling of coal beds.
