The scale of South Georgia is absolutely overwhelming. Massive mountains grace the horizon. Glaciers are colossal. Penguins come by the thousands. Fur seals are everywhere you look. And the island itself is 2,000 km from the nearest mainland – isolation beyond description. I took this from our ship, the Vavilov, on an early morning at Gold Harbour, a place of incredible beauty. This is a penguin highway, which is simply a path of least resistance the animals continuously follow. In the back is the rapidly receding, spectacular Bertrab Glacier. By the way, the Canon 100-400 was by far my most used lens on the trip. Photo by Paul Zizka Photography.
