Lemaire Channel, Peterman Island, Booth Island

How do you express the inexpressible?

Today we navigated the narrow Lemaire Channel, explored in the footsteps of the French explorer Jean-Baptiste Charcot on Peterman and Booth Islands, and kayaked flay-calm seas among icebergs and alongside a friendly humpback whale. There were clouds clinging to the lofty peaks on the Antarctic continent, a snow squall that snuffed out the sun, lazy leopard seals sleeping on ice floes, and curious penguins that welcomed our presence.

In truth, there is no way to express what we experienced today. It is personal to each and every one of us. Antarctica has overwhelmed our senses. But perhaps nothing we experienced could eclipse how our day ended.

It was just before dinner when the National Geographic Endeavour approached a huge tower of ice in Penola Strait. The scene was perfect in every way, complete with an arch sculpted from this glacier ice born from the Antarctic ice sheet. It was a fitting end to a day that lasted what seemed like an eternity.
