Glacier Calving Bay

Glacier Calving Bay is an original illustration set in Prince William Sound, Alaska. It lies in high latitudes, where the climate is subarctic — long freezing winters, brief summers.

A towering crevassed glacier front meets the water, one large ice block caught mid-collapse with a splash rising. A field of drifting brash ice covers the bay. Steep dark forested walls rise on both sides, and the long summer evening light is cold and gold.

Why does a glacier break apart where it meets the sea?

A glacier reaching tidewater calves because the ice front floats and breaks rather than melting back gradually — the collapse is mechanical. Crevasses record where the ice stretched over uneven bed. Steep walls meeting deep water in a straight trough is a fjord: a glacial valley drowned by the sea after the ice retreated.
