The Northern Rio Grande National Heritage Area. Santa Fe, Rio Arriba, and Taos counties, New Mexico.

Estimates of the probability of future earthquake activity are difficult to make in areas where historical seismicity may be low or absent, but where young fault scarps attest to recent or ongoing tectonism. Three non-Poisson models, a Weibull model, a Gaussian model and a lognormal model, are used to estimate the earthquake hazard for one such area, the northern Rio Grande Rift. This portion of the Rio Grande Rift displays numerous Holocene faults attesting to ongoing tectonism, but displays essentially no historical seismicity. The earthquake hazard for the Sangre de Cristo fault zone from Taos, New Mexico to Salida, Colorado calculated using these models is remarkably consistent (probability of at least one Mo = 7 earthquake in the next 50 years ∼ 2.5 × 10−3), with increased hazard for the Sangre de Cristo fault in north San Luis Valley (∼5.0×10−3) and near Taos (∼1.0×10−2) due to the long holding times along these segments.

ABSTRACT Three native trouts occur in the southwestern United States. The Rio Grande cutthroat trout Oncorhynchus clarkii virginalis persists in New Mexico and southern Colorado on the Santa Fe, Carson, and Rio Grande national forests and private lands. The Gila trout O. gilae and the Apache trout O. gilae apache (also known as O. apache) occur in isolated headwater streams of the Gila and Little Colorado rivers on the Gila and Apache- Sitgreaves national forests and Fort Apache Indian Reservation in southwestern New Mexico and east-central Arizona, respectively. For more than two decades, intensive management has been directed at the Apache, Gila, and Rio Grande cutthroat trouts. Despite the efforts, their decades-long listed status remains unchanged for the Gila and Apache trouts, and the Rio Grande native is under consideration for listing. The objectives of this paper are to review the literature and management activities over the past quarter of a century in order to delineate why recovery and conservation have been so difficult for southwestern trout.

New Locations

Few traveling between Santa Fe, New Mexico, and the Rio Grande valley realize that they are traversing one of the most significant American Indian migration and settlement corridors in the Southwest, a well-watered and fertile floodplain that served to link peoples of the southern Rocky Mountains and the San Juan River to those of the Jemez range and Sangre de Cristo Mountains, and the Rio Grande, across some 300 miles. This chapter gives an overview of Pueblo (Tiwa, Tewa, Towa, Keres, Hopi, and Zuni), Apache, Navajo, and O’odham histories, and reveals a dual process of migration and place making across a millennium. The Southwest has a high variability in seasonal precipitation, and its peoples have demonstrated creative and adaptable cultures that allowed for movement to new locations and the creation of new homelands as a crucial aspect of their survival.

Increase Soil Moisture

Rio Grande Anasazi in the fourteenth and fifteenth centuries A.D. mulched hundreds of garden-sized plots with pebbles to increase soil moisture, reduce erosion, extend the growing season, and increase crop yields. This paper reports on the construction and configuration of pebble-mulch gardens in New Mexico, focusing particularly on those in the Galisteo Basin. Surfaces adjacent to these gardens were scraped and pits were excavated to collect gravel, which was placed over garden surfaces in layers 5 to 11 cm thick. Gardens averaged 15 x 23 m in size, although both size and shape were highly variable, and they collectively covered an area of 41,000 m2 Although this unique agricultural strategy has been shown to be effective, construction was limited to sites with natural gravel deposits, pebbled surfaces inhibited the recycling of crop wastes, and such gardens never became as widely used as more traditional field forms.
