- Geological Maps on the Web - This is a collection of new geological mapping that could not be published elsewhere for some reason. It is all in the Mojave Desert and Basin and Range provinces. The Arc e00 files and Shape files are available for the actual data. There are pdf, eps, gif, and other file formats on line for those who do not need the digital data.
