A blue ice cavern stretches above a meltwater stream, its scalloped ice roof catching light through translucent bands. Fine icicles hang from the uneven surface, and pale trapped textures interrupt the deeper cobalt color. The stream curves toward a small daylight opening, giving the immense interior a clear direction.

Dark volcanic gravel forms low banks along the water, where wet stones provide a rough contrast to the rounded ice overhead. The scene is almost entirely blue and charcoal, with only the pale opening breaking the cool palette. Its sense of scale comes from the long sequence of arches and the narrowing stream rather than from a person in the frame.
