Geological Survey/National Park Service (USGS/NPS) geologic mapping project is to produce several 1:100,000-scale digital geologic maps of this region to provide connectivity for the regional geological framework of the southwestern Colorado Plateau and eastern Great Basin provinces. The database maps...
Addressing these and other land-use issues requires accurate and up-to-date geologic maps and related topical data. A major goal of our integrated work is to revise existing geologic mapping and remap poorly understood areas in order to create state-of-the-art, digital databases at a level ...

When I was in college, I encountered a textbook passage that helped me visualize geologic time. The author, Don Eicher of the University of Colorado, imagined Earth’s entire 4.54 billion year history compressed into a single year. He pointed out that, in this calendar, Earth’s first organi...
The face, as it was advanced, was mapped once during each shift (8 hours) at a scale of 1 inch to 2 feet. In support of the rock-mechanics instrumentation and geophysical programs, geologic maps were made of one wall or the other at 1 inch to 5 feet for a 50-foot distance on ...
