has been mounted in the hallway across from SCI 137 among many other geology displays (click to enlarge). While this isn't exactly a new map - it was published in 2005 - it is considered to be the best depiction of the geology of North America. (The map can be purchased from the Geological Society of America.) That's Professor emeritus E. Kiver examining the colorful cartograph.

Acknowledgments go to the Bu Dad who helped with constructing the mounting panels, and to CS who assisted with the Plexiglas overlay.
