US Forest Service Air Quality Cams
Three Forest Service cameras to pick from -- Pasaytan Wilderness, and two very handy cameras for Mount Hood and the Gorge. All are updated at 15 minute intervals and have 24-hour archived images.
National Park Service Air Quality Cams
For the Pacific Northwest, the Park Service has cameras at Olympic, North Cascades and Mount Rainier. Nothing at Crater Lake (yet), so will have to stay tuned for that one. Like the USFS cams, the Park Service cameras update at 15-minute intervals, and have 24-hour archives.
