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).

The Rio Grande is the fourth longest river in North America. Flowing nearly 2,000 miles from Colorado to the Gulf of Mexico, in New Mexico it occupies the Rio Grande Valley, where it provides water for habitat, agriculture, and a growing population. In northern New Mexico, where the river has carved a pair of spectacular canyons, the Rio Grande also provides some of the most exceptional recreation opportunities and scenery in North America. This comprehensive, spiral bound, waterproof, 122-page river guide provides detailed, full-color maps of 153 miles of the Rio Grande, from Lasauses, Colorado to Cochiti Dam in New Mexico. Divided into eleven river stretches—including the popular whitewater runs in the Taos Box, Racecourse, and White Rock Canyon—the guide covers stretches that range in difficulty from placid canoe tours to gripping kayak descents. The river maps are developed on an aerial photographic base (digital orthophoto quads), allowing the user to more easily identify locations.

The geology of the region is likewise exceptional. The river spills from the San Juan Mountains into the Rio Grande rift, where several million years of erosive action have exposed a geologic cornucopia, including three major volcanic fields (including the Jemez supervolcano), seismically active faults, extinct Pleistocene lakes, and ancient rocks of the Rocky Mountains. The guide uses non-technical language and lavish illustrations to interpret the evolution of this magnificent landscape.

Although the focus of the guide is on geology and landscape, the guide is packed with information and photos on geography, hydrology, climate, boating safety, river management, rock art, and much more. Providing detailed information on access and trails, history and landscape, railroads and mining, this guide is also an invaluable resource for hikers, anglers, cyclists, day trippers, historians, philosophers, and casual visitors.

The Geologic Map of the Mount Taylor Volcano Area, New Mexico is a 1:36,000 compilation of six recent NMBGMR 1:24,000 geologic quadrangles that encompass this extinct composite stratovolcano. Mount Taylor is New Mexico’s second-largest volcano after the Valles Caldera in the Jemez Mountains. This timely map and accompanying report, resulting from over a decade of thorough work, synthesizes the current geologic understanding of such an important landscape feature of the state.

For such a complex volcanic landform, the report provides an exhaustive description of the volcano area in an easy-to-read format. In addition to providing a detailed description of each of the map’s 339 units and dikes, it documents the volcano’s history and history of research, its geochemical and petrographic composition, the phases of its construction ranging from the initial to the terminal eruptions, 3.72–1.26 million years ago, and its subsequent erosion, resulting in the summit Amphitheater and its extensive apron of debris. It describes the surrounding volcanic centers, the structure of the area, and the extensive dikes and maars. After touching on the water resources, hydrothermal alteration and mineralization, and geothermal potential, the report concludes with a conceptual model of volcano evolution.

Available folded or rolled on field-durable media. There is also a puzzle version of this geologic map.

This vibrant 19 x 27" 1000 piece puzzle version of our soon to be released Geologic Map of Mount Taylor (expected late 2019) will keep you from finishing that geochemistry paper you should be writing.

The suitability for managed aquifer recharge (MAR) in the eastern Albuquerque metropolitan area was mapped using weighted overlay analyses. The study area extends from the Rio Grande eastward to the Sandia Mountains and from Sandia Pueblo southward to ~1 mi (~2 km) south of Tijeras Arroyo. This area is under the jurisdiction of the Albuquerque Bernalillo County Water Utility Authority (ABCWUA), which will likely be the main user of this work.

We produced two maps for MAR suitability, each with a grid cell resolution of 100 x 100 m: one showing the suitability for deep-injection recharge (i.e., pumping water directly into the saturated zone) and the other for shallow recharge (by infiltration or vadose- zone injection). These maps depict three color-coded suitability bins—low suitability, moderate suitability, and high suitability—as well as exclusionary zones. A third map predicts the susceptibility of different areas to soil hydrocompaction, a potential adverse consequence of infiltrating surface water into certain types of previously unsaturated soils.

This report includes map plates showing results of analyses as well as GIS data for the plates. Appendices also provide source data and analyses steps (see below).

The Valles caldera, located in the heart of the Jemez Mountains in north-central New Mexico, is the world’s premier example of a resurgent caldera, a giant circular volcano with an uplifted central floor and a near-perfect ring of roughly 15 postcaldera lava dome and flow eruptions.

This new Valles caldera map and cross sections represent the cumulative research efforts of countless geologists over the past 40 years, and several state and federal agencies. GM–79 compiles detailed geologic mapping completed in the past eight years from parts of the nine 7.5–min USGS topographic quadrangles that encompass the caldera. More than 150 map units are described in detail. Also incorporated are new geochronologic data and recent refinements to nomenclature.

Available folded or rolled (additional charge of $5.00 for rolled).
$18.95 plus $6.50 for shipping and handling and 5% gross receipts tax for NM residents.

There is also a bandana and puzzle version of this geologic map available.

Few places in the U.S. boast as rich a diversity of landscape and public lands as northern New Mexico. Here in one volume is an authoritative overview of the geology of these parks, monuments, and public lands, with information on the regional setting, the rock record, and the most prominent geologic features. The book includes chapters on nine national parks and monuments, seventeen state parks, and many of the most popular Bureau of Land Management and U.S. Forest Service units in this part of the state. Also included are chapters on two of our newer units, the Valles Caldera National Preserve and Kashe-Katuwe Tent Rocks National Monument. With nearly 300 full-color geologic maps, graphics, and photographs, the book is a perfect introduction to the some of New Mexico's most significant geologic landscapes.

East-central New Mexico is dependent on groundwater from the High Plains aquifer for agricultural, municipal, industrial, and domestic uses. Ongoing declines of water levels in the High Plains aquifer are well-known and have led residents and decision-makers to speculate on the usable life of the aquifer. This Bulletin presents aquifer lifetime projections for eastcentral New Mexico based on projecting historical water-level trends into the future using over 1,500 wells. Projections for the useful lifetime of the aquifer for agricultural and municipal/domestic-use scenarios are described. Several quantitative measures of the reliability of the results are presented. The results are stark, with projected usable lifetimes in many areas only ten years or less. Much of the region already has insufficient saturated thickness for the operation of large-capacity irrigation wells.

The Raton-Clayton area is known for its intertwined geologic, biologic, and human histories. Over thirty years have passed since the NMGS Fall Field Conference was last held in northeastern NM. Recently, numerous workers have focused on Mesozoic stratigraphy, Laramide tectonics, late Quaternary volcanism, landscape evolution, groundwater characterization, and induced seismicity. The field conference will highlight aspects of the current and ongoing research. The area hosts spectacular and diverse geology, often overlooked by travellers to this part of the state. We will examine the geologic, biological, and human histories of the mesas, volcanic peaks, and numerous valleys that riddle the landscape of the hi-lo country.
