This snazzy 2016 map of the unique Valles Caldera National Preserve just over the hill from Los Alamos, New Mexico, shows the geology of vulcanism as clearly as any you can find. The map part perfectly illustrates the ring that defines the caldera and the back side the development thereof over the eons. Now on tear proof synthetic paper. Revised in 2016 showing roads, trails and points of interest
