Silver and gold have been found in 163 mining districts and other geographic locations in New Mexico. More than 3.2 million oz of gold and 117 million oz of silver have been produced in New Mexico from 1848 through 2000. Production from most districts has been small; however, 14 districts have produced more than 3,000,000 oz of silver, and together they account for approximately 80% of the total silver production in New Mexico. Ten districts have produced more than 150,000 oz of gold, and together they account for approximately 96% of the total gold production in New Mexico. Silver and gold are found in 14 distinct types of deposits that range in age from Proterozoic through Holocene. Five deposit types have produced significant gold and/or silver as the primary product: placer, volcanic-epithermal, Great Plains margin (alkaline-related), carbonate-hosted silver-manganese replacement, and Laramide vein. Four deposit types have produced significant silver and gold as byproducts of base-metal production: carbonate-hosted lead-zinc replacement, Laramide skarn, porphyry copper, and Proterozoic massive-sulfide. The five remaining deposit types with minor silver and/or gold production are: copper-silver (±uranium) vein, Rio Grande rift, Mississippi Valley-type, sedimentary-copper, and vein and replacement in Proterozoic rocks. All 163 mining districts are described in the text and located on the 24" x 29" map. The text also describes the classification of silver and gold-bearing deposits into 14 distinct types. RM-21 supersedes RM-15.

New Mexico, with some of the most significant energy reserves in the lower 48 states, is a major player in this country's conventional energy production. The state also has enormous potential for developing significant renewable/alternative energy resources, including solar and wind. This anthology of 30 articles is a timely look at how energy works in New Mixico today, with an eye toward the promises and challenges that lie ahead. Produced in conjunction with the second annual Decision-Makers Field Conference in may 2002, this volume is an important contribution to the literature on energy in New Mexico. 152 pages, 47 tables, graphs, and illustrations, 32 color photographs, and 23 page-size maps.

This color state geologic map, published in July 2003, is the first geologic map of New Mexico to be published at this scale since 1965. Close to 20 years in the making, this map reflects the collective efforts of geologists from throughout the state. Over 100 geologic units are represented. Two sheets, including a detailed key and extensive references. 54" x 47" and 50" x 42"

Geologic Map of New Mexico

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 135-mile Rio Chama of northern New Mexico is a major tributary of the Rio Grande. From its alpine headwaters at the Continental Divide of the glaciated San Juan Mountains in southern Colorado, this hidden gem flows across the Colorado Plateau in a spectacular canyon cut into Mesozoic sedimentary rocks, in places up to 1,500 feet deep. Towering, vibrant, sandstone cliffs, heavily wooded side canyons, superb camping, and a diversity of historical sites offer an outstanding wild river backdrop for the boater, angler, hiker, or camper. This book contains detailed river maps of the seven sections of the Rio Chama, plus its three resplendent reservoirs, from the Colorado headwaters to its confluence with the Rio Grande near Española. The Chama Canyon section, below El Vado Dam and through the Chama Canyon Wilderness, is one of the finest, multi-day, whitewater trips in the Southwest.
