Mexican Americans in West Texas is an essential work investigating the human geography of a key Texas region. Its scope gives primary attention to the counties generally encompassed by the Edwards Plateau and the Trans-Pecos region, which extends from just past the Hill Country counties of Mason, Gillespie, Kerr, and Bandera, to approximately the Pecos River but also embracing the conterminous subregion that geographers identify as the Permian Basin. This book honours the conventional definition of the Trans-Pecos region, treating it as beginning at the Pecos River and heading west to Hudspeth County, the farthest reach of this endeavour.A reliance on secondary works very much dictated the time parameters of the study. For the most part, the many county histories, the several collections of essays, and the numerous articles from venues such as the Journal of Big Bend Studies, the West Texas Historical Association Year Book, and the Southwestern Historical Quarterly decreased their coverage of historical occurrences in the region somewhere around the last decades of the twentieth century. Considered broadly, the book may be deemed a synthesis of published accounts that capture the course of events and the flow of historical currents that transpired in the vast expanse west of the 100th meridian. Mexican Americans in West Texas speaks to the existence of many disparate and disunified secondary sources on West Texas, a region that has been too long overlooked in the history of the Lone Star State.
