This resource has been around for awhile but it hasn't lost its potential to enrich class discussions on structural geology and geomorphology. The actual Gallery has links to QuickTime Virtual Reality (QTVR) and QuickTime (QT) movies of digital topography. Each movie consists of a 3D perspective of the map area that the user can rotate using the mouse to view the area from any direction. Some movies have contours draped over topography or let you raise and lower a water plane, so that you can better visualize how the contours are portraying the shape of the land.
