Mount Rainier National Park
Mount Rainier, as seen from the Paradise area webcam. The cam was recently upgraded to higher-resolution, wider-angle camera.
Some of the cameras have been upgraded. The one that looks at the mountain from the Paradise area was upgraded today to a higher-resolution, wider-angle camera. You can check it out here.
You can find other webcams in the park here. (Some of them are down for the winter, but many are still up and running.)
It's great fun to look at them -- especially on those days you're stuck behind a desk and wish you weren't.
Other natural areas around here also have webcams for your viewing enjoyment.
A while back, I saved an image from one of the volcano cams with a fly on it. It's been 8 years and I still have that image because I find it so amusing. Apparently I'm easily entertained.
Ahem. Back to the subject at hand. Webcams.
North Cascades National Park also has one, although it's down for maintenance at the moment, and is just an archived image. You can find that here. (Bookmark it for a slow day.)
Olympic National Park has several webcams right here. The one at Hurricane Ridge is lovely. They also have one showing the area where the Glines Canyon and Elwha dams were removed. If you check back on those from time to time, you can see the areas changing.
