Our second day in the spectacular polar wilderness of Marguerite Bay took us to the coast of the Antarctic Peninsula along its inner, eastern shore. Here, surrounded by jagged peaks reaching up vertically from the icy waters, we found the soaring promontory of pink granite known as Red Rock Ridge and went ashore among the Adelie penguins nesting at its base. The breeding season of the penguins is in full swing with large, fat chicks in the nests and adults busily coming and going with a constant supply of tasty krill. Later in the afternoon, we cruised into nearby Neny Fjord, where we found dozens of crabeater seals and had a glimpse of an emperor penguin far out across the fast ice.
