The new Texas Geology Web Map Viewer is an interactive web-based tool that allows a broad range of users to explore the geology of the Lone Star State at a scale of 1:250,000. Users can navigate the map with a simple click-and-point tool, or by using the location search tool to search for common geographic place names, latitude/longitude coordinates, and other areas of interest. The interactive map viewer allows users to turn data layers on or off, identify layers of interest, and retrieve detailed information about each geologic formation, such as the feature name, geologic age, and feature description.
