Thousands of people both known and unknown have roamed through the Berkshires to listen to music at Tanglewood or to take a long walk up Mt. Greylock. This enchanting guide to the natural history of this ancient mountain range in western Massachusetts was created by Professor Henry Art of Williams College as part of his work with his students. The homepage provides a bit of background history on these hills and valleys, along with some nice images. Visitors can then proceed through the Locations tabs to look over such notable landmarks as Mount Greylock, Petersburg Pass, Stonehill, and the Hoosic Floodplain. Each of these tabs contains maps, directions, images, and even some videos. It's a site that might inspire a new interest in natural history or perhaps your own jaunt out to this distinct region.
