Freshwater Bay (Alaska)


Freshwater Bay is an inlet in the U.S. state of Alaska. It is situated on the eastern shore of Chichagof Island, Chatham Strait, in the Alexander Archipelago. Overlying rocks of cherty limestones of Silurian age stand nearly vertically and are over thick. On the northeast side of the bay, a thick series of melaphyre lava flows and tuffs are interstratified with limestone of Upper Devonian age.
