Antarctica.

I’d never before had the experience of beholding scenic beauty so dazzling that I couldn’t process it, couldn’t get it to register as something real. A trip that had seemed unreal to me beforehand had taken me to a place that likewise seemed unreal, albeit in a better way. Global warming may be endangering the continent’s western ice sheet, but Antarctica is still far from having melted. On either side of the Lemaire Channel were spiky black mountains, extremely tall but still not so tall as to be merely snow-covered; they were buried in wind-carved snowdrift, all the way to their peaks, with rock exposed only on the most vertical cliffs. Sheltered from wind, the water was glassy, and under a solidly gray sky it was absolutely black, pristinely black, like outer space. Amid the monochromes, the endless black and white and gray, was the jarring blue of glacial ice. No matter the shade of it—the bluish tinge of the growlers bobbing in our wake, the intensely deep blue of the arched and chambered floating ice castles, the Styrofoamish powder blue of calving glaciers—I couldn’t make my eyes believe that they were seeing a color from nature. Again and again, I nearly laughed in disbelief. Immanuel Kant had connected the sublime with terror, but as I experienced it in Antarctica, from the safe vantage of a ship with a glass-and-brass elevator and first-rate espresso, it was more like a mixture of beauty and absurdity.
