It's one thing to read that piedmont glaciers form when ice spreads out after squeezing through a narrow valley. But the concept is more likely to stick in your mind if you see the result, as in an aerial photo of sprawling glaciers on Axel Heiberg Island in northern Canada. Glaciers Online from Swiss teacher Jürg Alean and glaciologist Michael Hambrey of the University of Wales in the U.K. is a boon for visual learners. The pictorial introduction matches nuggets of glacier information with spectacular photos from all over the world. To distinguish cirque, outlet, and other glacier types, for example, the site spirits you from Antarctica to the Alps to the Grand Tetons. Visitors can also see how moving glaciers shape the landscape, bulldozing valleys such as Glencoe in Scotland.
