The writings of the U.S. scholar Philip Wayne Powell have had an enduring influence on the historiography of colonial Mexico and the Spanish borderlands. But his writings have never been examined as a unified corpus, and so the deeply reactionary political ideology that lay behind them has never been well understood. By analyzing Powell’s political convictions, this article shows how contemporary scholarship on the conquest of northern Mexico can emerge from Powell’s long shadow. Los escritos del estudioso estadounidense Philip Wayne Powell han ejercido una influencia perdurable sobre la historiografía del México colonial y las zonas fronterizas españolas. Sin embargo, dichos escritos nunca han sido examinados como un corpus unificado, de manera que la ideología política profundamente reaccionaria detrás de ellos nunca ha sido bien comprendida. Al analizar las convicciones políticas de Powell, el presente artículo muestra cómo puede surgir un conocimiento contemporáneo sobre la conquista del norte de México a partir de la larga sombra de Powell.

Between 1820 and 1827 approximately 1,800 U.S. citizens immigrated to northern Mexico as part of that country’s empresario program, in which the federal government granted foreigners land if they promised to develop and secure the region. Historians have long argued that these settlers, traditionally seen as the vanguard of Manifest Destiny, were attracted to Mexico for its cheap land and rich natural resources. Such interpretations have lent a tone of inevitability to events like the Texas Revolution. This article argues that the early members of these groups were attracted to Mexico for chiefly political reasons. At a time when the United States appeared to be turning away from its commitment to a weak federal government, Mexico was establishing itself on a constitution that insured local sovereignty and autonomy. Thus, the Texas Revolution was far from the result of two irreconcilable peoples and cultures. Moreover, the role that these settlers played in the United States’ acquisition of not just Texas, but ultimately half of Mexico’s national territory, was more paradoxical than inevitable.

The recent discovery of a pit house village, 40 km northwest of Monterrey, challenges the conventional view of inland northeastern Mexico as the domain of purely nomadic hunters and gatherers throughout prehistory. Las Casitas consists of fifty-three subterranean rooms and forty-eight smaller depressions aligned in three slightly arcuate tiers in a small valley adjacent to Boca de Potrerillos, an extremely large open campsite and petroglyph complex that is now an archeological park. Other features of the site are some 325 hearths that surround the depressions and a very limited artifact assemblage numbering only thirty-seven items. Two hearths produced radiocarbon samples that date site occupancy to approximately a.d. 1450, just prior to the arrival of the Spanish in the New World. Las Casitas provides the first evidence of semi-sedentary, surplus producing populations in central northeastern Mexico.

Understanding soil moisture behavior in semi-dry forests is essential for evaluating the impact of forest management on water availability. The objective of the study was to analyze soil moisture based in storm observations in three micro-catchments (0.19, 0.20, and 0.27 ha) with similar tree densities, and subject to different thinning intensities in a semi-dry forest in Chihuahua, Mexico. Vegetation, soil characteristics, precipitation, and volumetric water content were measured before thinning (2018), and after 0%, 40%, and 80% thinning for each micro-catchment (2019). Soil moisture was low and relatively similar among the three micro-catchments in 2018 (mean = 8.5%), and only large rainfall events (>30 mm) increased soil moisture significantly (29–52%). After thinning, soil moisture was higher and significantly different among the micro-catchments only during small rainfall events (<10 mm), while a difference was not noted during large events. The difference before–after during small rainfall events was not significant for the control (0% thinning); whereas 40% and 80% thinning increased soil moisture significantly by 40% and 53%, respectively. Knowledge of the response of soil moisture as a result of thinning and rainfall characteristics has important implications, especially for evaluating the impact of forest management on water availability.
