Built for photographers
Fog-Index is built by James Lorentson, a Pacific Northwest landscape photographer. The photographs on this page were made in the western Columbia River Gorge near Beacon Rock; the live forecast and webcam are anchored farther east at Underwood and Hood River, where a clear view across the river makes the atmospheric setup easier to validate.
