After a 20-year hiatus, the 2018 NMGS Fall Field Conference will showcase the geology of south-central New Mexico with emphasis on the Doña Ana Mountains and surrounding regions near Las Cruces. The Las Cruces area is situated in the northern part of the Chihuahua Desert and is noted for a wide variety of geologic and geomorphic features as well as the recently-designated Prehistoric Trackways National Monument (2009) and Organ Mountains-Desert Peaks National Monument (2014). New data and topics discussed in this guidebook include regional geologic structure and tectonics, stratigraphy and paleontology, hydrogeology, petrology and geochemistry, volcanology, economic geology and mineral resources, mining history, as well as a wealth of new igneous and detrital geochronologic and thermochronologic ages from Precambrian- Cenozoic rocks. This volume includes detailed road logs of the Las Cruces region as well as four mini-papers and sixteen peer-reviewed technical research papers.

There are two versions of this guidebook available, the complete guidebook (218 pages), and a version with just the road logs that is spiral bound (68 pages).
