Approaching Deception Island on a misty morning. This is looking through "Neptune's Window" just before turning into the caldera through "Neptune's Bellows" from the outside.
The eastern side of Neptune's Bellows, a narrow gap in the caldera that serves as a nautical entrance (so named because of the tremendous winds that are sometimes funneled through it).
The edge of the caldera wall from inside Whaler's Bay, a small bay immediately inside the east edge of the caldera entrance used, as the name implies, as a whaling station back when whaling was allowed.
The black sand beach of Whaler's Bay. Note what looks like steam; that's what it is. This is, after all, still an active volcano, last erupting in 1970.
Looking the opposite direction (south) along the beach to the caldera wall surrounding Whaler's Bay, the eastern margin of the entrance to the caldera.
After walking south to the end of the beach, we cut up-slope to the east to Neptune's Window. This and the next two photos are looking through Neptune's Window, here the left side (east).
Seemingly confused chinstrap penguins not sure which way to go. It's almost impossible to look at penguins without laughing, or at least smiling, and wondering, in an anthropomorphic way, what they're thinking!
