This text explores the natural history of Texas and more than 2900 springs in 183 Texas counties. It also includes an in-depth discussion of the general characteristics of springs - their physical and prehistoric settings, their historical significance, and their associated flora and fauna.

Illustrates events in Texas history and geography through 64 maps and brief essays.

Describes the peyote plant, the birth of peyotism in western Oklahoma, its spread from Indian Territory to Mexico, the High Plains, and the Far West, its role among such tribes as the Comanche, Kiowa, Kiowa-Apache, Caddo, Wichita, Delaware, and Navajo Indians, its conflicts with the law, and the history of the Native American Church.

In 1718, the Spanish settled San Antonio, partly because of its prolific and breathtaking springs—at that time, one of the largest natural spring systems in the known world. The abundance of fresh water, coupled with the Spanish colonial legal concept that water was to be equitably shared by all settlers, led to the building of the system of acequias (canals or ditches) within the settlement. The system is one of the earliest and perhaps most extensive municipal water systems in North America. This book offers a meticulous chronicling of the origins and often-contentious development of water rights in San Antonio from its Spanish settlement through the beginning of the twentieth century.

This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i.e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst.
