The presence of coal in the Tertiary Kenai formation of western Kenai Peninsula has been known since 1880, chiefly as exposed along the north shore of Kachemak Bay and the adjoining east shore of Cook Inlet (fig. 1). Several early attempts were made to develop a commercial mine in this area in the period 1888-1902 but none progressed beyond the prospecting stage and little coal was produced. In 1915 the mining of coal-was started at the Bluff Point mine, 1 1/2 miles west of Homer. Available records indicate that this mine produced between 20,000 and 25,000 tons of coal before closing in 1324. No further attempt at mining was made until 1946, when the Homer Coal Corporation began development near the site of the old Bluff Point mine. Development work during 1946 and 1947 included construction of a truck-loading bunker, mess hail, bunkhouse, and an incline end hoist for raising coal from the tunnel in the face of the beach bluff. Only a small amount of underground work was done in 1946 and 1947, and practically none in 1948.
A preliminary step toward more extended investigation of the coal deposits of the Homer district was made by the writer, accompanied by T. J. Jolley of the U. S. Bureau of Mines, in the summer of 1946. Several days were spent in examining the principal coal exposures near Homer and collecting samples to determine the desirability of more detailed investigation.
Detailed examination of the coal deposits of the Homer district was started by the Geological Survey in 1947. The period July 17 to September 14 was spent by the writer, assisted by H. C. Wagner, geologist, and L. A. Hale, field assistant, in reconnaissance of isolated coal exposures in an area extending several miles north of Homer, and in measuring detailed stratigraphic sections in the bluffs just north of Homer between Coal (Bidarki) and Fritz Creeks.
