The first breath of Alaskan winter is a physical thing — sharp, cold, and immediate. You step from the company office in Seward into a world hushed by snow: spruce boughs sag under powder, the air tastes metallic, and the silhouette of Exit Glacier slices the sky. For the next four hours the day alternates between speed and silence. On a late-model snowmobile you push through open bowls and along cross-country trails, the machines hissing like industrial wolves. Then you swap the throttle for snowshoes, padding out across a moraine where the glacier’s face creeps toward the valley, blue ice daring you to come closer.
