Heat River is a photographic study of a rivermouth. The river empties into Lake Superior in a remote part of Michigan. With this work I aim to convey the rivermouth’s sheer particularity in excess of a stable identity. All of these images were made within feet of one another. Each is a long-exposure photograph; most are exposures of four to eight minutes. They were made at the tail-end of dusk. These exposures brighten dim light beyond what eyes alone can see. Because of this, the time of day often appears androgynous. Some of these images are lit by both the sun and the moon. In many of these images the light is hazy and muted. This is from the smoke of forest fires in Ontario thickening the air over Lake Superior.
