Deception Island near Pendulum Cove's thermal waters in Whaler's Bay, a protected harbor. Deception Island is the site of a circular flooded volcanic caldera. On the shore are rusting remains of whaling operations (1911 to 1931) and the ruins of a WWII British base, Port Foster (1944-1967). Evacuated after a volcanic eruption, then closed permanently in 1969 after another eruption. Chinstrap penguins are nearby in the steam of the volcanics that are still warming the beach sand at Whaler's Bay. Antarctica.
