Morning light slides across spruce and tundra as your van pulls onto the Richardson Highway and the Alaska Range unfolds ahead. The mountains don’t wait — glaciers and ridgelines push a cold presence into the valley — and wildlife often appears roadside: moose browse, caribou cross without hurry. After roughly 2.5 hours of highway, you step where the trail begins and walk toward an ice cave carved into a moving mass of Castner Glacier.
