There are active volcanoes in Alaska, especially now including Mt. Redoubt. It appears likely to erupt as of this writing, and I'm not expecting to be on the top of things when it does. The Alaska Volcano Observatory is the best source of current information, and they are using twitter at @alaska_avo for updates.
Here are some sources for Alaska volcano maps - so you know where things are, how far apart the various places are, and what might be downwind.
Mt. Redoubt is in the Cook Inlet part of Alaska, near Anchorage. This map shows distances and links to the AVO's pages on the various volcanoes in this area. Mt. Redoubt is also historically known as Ujakushatsch, Viesokaia, Goreloi, Mirando, Redoubt Volcano, Redoubt, Mt., Yjakushatsch, Burnt Mtn., Goryalaya, Redoute Mtn. and Redutskaya, Sopka.
The Smithsonian has a collection of satellite imagery from volcanoes around the world. Here are their satellite photos of Mt. Redoubt from the ASTER Volcano Archive. These will load into Google Earth as KML files as well. The "plain" imagery from this are about 30 megapixels apiece and are from 2000; here's a piece of one of them.
