For college professors looking for engaging activities that will instill the basic constructs of structural geology, these visualizations will provide welcome sustenance. Topics include Orogeny, Uplift and Erosion, Isostasy, Maps and Mapping, Folds, Faults, and Shear Zones, Sandbox Movies, Microstructures and Fabric, and Stress and Strain. Within each topic area there are a number of visualizations that may be integrated into undergraduate classes and projects. For example, within Uplift and Erosion readers will find a depiction of the Plio-Pleistocene tectonic shortening of the Transverse Ranges in California, as well as a visualization that "shows a cut-globe view of the continental collision between India and Eurasia from 60 million years ago to present." Anyone with an interest in geology and the earth sciences will find much to enjoy on the site.
