Summary:

Named from Cedar Cove on southwest shore of Freshwater Bay. Measured type section extends from point on west shore of Cedar Cove, about due west of north tip of Cedar Island, northwestward along shore for about 3 mi, southeastern AK. Divided into lower member of dominantly thin-bedded argillite and upper member of dominantly limestone at type section. Is 2660 ft thick. Overlies Kennel Creek limestone (new). Unconformably underlies Freshwater Bay formation (new). Shown on geologic map of Freshwater Bay area, Chichagof Island, AK. Age is considered Middle and Late(?) Devonian based on fossils.

Summary:

Shown on geologic map of Chichagof, Baranof, and Kruzof Islands, southeastern AK. Unit is extended to outcrops along Chatham Strait on north shore of Tenakee Inlet, in Hoonah area, and throughout region between Port Frederick and Icy Strait. Upper limestone member exposed in Port Frederick-Icy Strait area shown separately on map. Also lower clastic member (up to 3000 ft thick) shown separately from Cedar Cove Formation undivided. Age is Middle and Late Devonian based on fossil evidence (CYRTOSPIRIFER fauna of Frasnian age identified by J.T. Dutro, Jr., written commun., 1958).
