A Web page I visit every day is the Mt St Helens webcam. I like visiting it, because it shows how dramatically weather changes on mountain tops: fog, snow, rain, dust storms, and sunny days. Sometimes icicles dangle in front of the camera lens; other time, a fly or beetle rests on the lens.
(The mountain is in Oregon USA, and in 1980 blew its top during a dramatic volcanic explosion. Steam and ash come out of a vent hole every day. The Web cam was set up on a nearby mountain, in the hopes of capturing any future eruptions.)
Yesterday morning's image was especially spectacular. In the image below, you can see the snow-covered canyons carved by the lava flow from 27.5 years ago. The mountain used to have a pointy tip, so the huge bowl represents the amount of rock that was blown away.
