Earth is warming in response to increasing atmospheric carbon dioxide. Global climate models project an average temperature increase across New Mexico of 5° to 7° F over the next 50 years. Other primary impacts are decreased water supply (partly driven by thinner snowpacks and earlier spring melting), lower soil moisture levels, increased frequency and intensity of wildfires, and increased competition and demand for scarce water resources. Snowpack and associated runoff are projected to decline substantially over the next 50 years, generating diminished headwater streamflow. Flow in the state's major rivers is projected to decline by 16% to 28%, and the frequency of extreme precipitation events, coupled with fire-driven disruption of vegetation in watersheds, is projected to at least double river sediment. The impacts of climate change on New Mexico's water resources are overwhelmingly negative.

The bulletin, which is the scientific foundation upon which New Mexico's 50-Year Water Plan is based, represents a compilation, assessment and integration of existing peer-reviewed published research, technical reports and datasets relevant to the broad topic of changes to New Mexico climate over the next 50 years, and resultant impact on water resources. This project, also known as the "Leap Ahead" analysis, also identifies significant data and modeling gaps and uncertainties, and suggests research directions to strengthen our understanding of climate and water resource changes

This calendar highlights photographs from the fine amateur photographers on staff at the New Mexico Bureau of Geology. We hold an annual internal contest, and the winning images are used for our calendar. These images were taken throughout the state, and most are geologically themed.

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 interior of this mug has a reproduction of our Geologic Map of the Valles Caldera. The caldera once was filled by a lake, but you can fill it with coffee, tea, or whatever else satisfies your inner volcanologist.

The Mt. Taylor area is a crossroad where geologic history, human history, and societal impacts intersect. Situated on the eastern edge of the Colorado Plateau and flanking the transition zone to the Rio Grande rift, Mt. Taylor is a late Pliocene stratovolcano located on the Jemez Lineament, an enigmatic NE-trending alignment of late Cenozoic volcanic centers. Mt. Taylor lies along the southeast margin of the San Juan Basin bounded by the Zuni (south) and Nacimiento (east) uplifts. Mt. Taylor also has some of the richest uranium deposits in the United States.

The human history of the Mt. Taylor region is no less compelling. Indigenous communities lived here for thousands of years despite Spanish conquest and the establishment of land grants. In the 1800s, the area was settled as part of a U.S. territory, bringing with it commerce such as the railroad and timber industries, and later the uranium boom and its lasting legacy. Additional corridors of commerce opened with Route 66, succeeded by Interstate 40. The designation of Mt. Taylor as a Traditional Cultural Property recognizes the mountain's importance to Native, Spanish and U.S. cultures.

The papers in this volume cover a spectrum of topics, ranging from geologic studies and mining history to the effects of mining on the population and the environment today.

There are two versions of this guidebook available, the complete guidebook (310 pages), and a version with just the road logs that is spiral bound (94 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.

This geologic road log describes the diverse geology exposed along the Cumbres & Toltec Scenic Railroad between Antonito, Colorado, and Chama, New Mexico. The booklet was designed for use on the annual "Geotrain" excursion offered by the Cumbres & Toltec Scenic Railroad each summer since 2011. The geologic journey begins in the San Luis Basin in the Rio Grande rift, traverses the southern San Juan volcanic field, and ends in the Chama Basin. The booklet includes a brief introduction to the regional geology of the area, a discussion of the engineering geology associated with building and maintaining the railroad, and descriptions of outcrops exposed in roadcuts along the rail line.
