In every direction, it’s ice and sky. Save for the camp itself–a few buildings, a loose scatter of science towers and bamboo flags–there’s not a landmark around. Instead, we look out on the ever-changing horizon. The interplay of weather, snow texture, and sunlight recasts the horizon with infinite variations. A crisp line, a subtle gradient, a broad sweep of haze. A spectrum of blues, purples, gold. Fog or clouds moving over the surface. Shadows across the wind-roughened surface.  It’s a constant companion, our early-warning for weather, the best show in town.
