On the Antarctica peninsula we were treated to a pod of Orcas hunting a seal on a small ice flow. Unable to dump the seal into the water, the Orcas gave up after 12 minutes, but the viewing was unbelievable. Of course, we participated in the ''Polar Plunge''. . . how could one not go to Antarctica and not go for swim? More spectacular landscapes, unique and massive iceberg sculptures, and thousands of Gentoo and Chinstrap penguins. Unpredictable weather and snow blowing sideways made you feel you were on a real expedition to this southern frontier.
