On the verge of spring, the silvery etching of a tree appears across the winter white of western Alaska. Interlaced branches of waking-up streams weave across the wetlands of the Yukon Delta and reach toward the sea. To the west, the sea is softening the frozen shoreline, and blue-green waters show through cracks and crevices in the ice.
