Through the use of computers and the Internet, and virtual globes such as Google Earth, we now have a way around the inherent limitations of depicting the third dimension on a standard paper geologic map. To help users gain this 3-D advantage, the UGS created an overlay of the new geologic map of the St. George 30′ x 60′ quadrangle in southwest Utah. This 3-D visualization brings the map to life, dramatically showing the relationship between geology and topography. A virtual field trip for the St. George 30′ x 60′ quadrangle, which uses placemarks to highlight selected geologic features, was also created.
