“…For deeper units, those below lithologic unit 86, we do not have as yet any new age determinations. Therefore, the assumption is continued that these rocks, as interpreted on the DeBarr cross section (Schmoll and Barnwell, 1984), are part of the Kenai Group (Wolfe and Tanai, 1980) and probably lie within the Tyonek Formation, as are similar rocks exposed in the Eagle River area (Wolfe and others, 1966).…”
