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.

The Belen area is uniquely situated along the Rio Grande rift; with the Basin and Range not far to the west and the Great Plains not far to the east, the geology here is diverse. The focus of this guidebook extends from Bernardo to Los Lunas and from the Manzano Mountains to the mesas west of the Rio Puerco. Many people travel this central New Mexico corridor along I-25, and this guidebook will provide a broad look at the geology in and around Belen. Topics include the southern Albuquerque Basin and the underlying structure relative to the Rio Grande rift flanks; tectonic events and metamorphic processes related to the Priest pluton emplacement in the Manzano Mountains; a late Paleozoic Lagerstätten uncovered in Carrizo Arroyo in the western mesas; and the travertine rock record and its modern-day analog. These topics are only a glimpse of what can be found in this guidebook’s five roadlogs, 28 papers, and 16 color plates.

There are two versions of this guidebook available, the complete guidebook (512 pages), and a version with just the road logs that is spiral bound (172 pages).

This Resource Map locates and describes 246 mining areas in New Mexico (excluding coal fields). The included booklet begins with a brief description of the history of mining in New Mexico and is followed by discussions of previous work, mining claims, the definition of a mining district, mining methods, and classification of mineral deposits. Short descriptions of individual mining districts and prospect areas in New Mexico are in Appendix 1. Appendix 2 includes metal production from selected districts. Appendix 3 is a summary of previous mining districts maps. This report updates File and Northrop (1966), Howard (1967), and Mardirosian (1971), the last comprehensive summaries of all mining districts in New Mexico.

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.

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.

This boxed set of six volumes provides the most comprehensive and extensive review of New Mexico’s energy and mineral resources to-date. Each volume focuses on the geologic nature of the resource, the history of the resource development in New Mexico, and their importance to the world and New Mexico’s economy. Written by New Mexico’s own experts in the fields, this set covers energy resources of petroleum, natural gas, coal, uranium, and geothermal, along with the resources of metals and industrial minerals and rocks.

This memoir is published jointly by the New Mexico Bureau of Geology & Mineral Resources and the New Mexico Geological Society.
