Long after irrigation and dams rendered the river a polluted trickle, Patrick Dearen went seeking out the crossings and the stories behind them. In Crossing Rio Pecos--a follow-up to his Castle Gap and the Pecos Frontier--he draws upon years of research to relate the history and folklore of all the crossings--Horsehead, Pontoon, Pope's, Emigrant, Salt, Spanish Dam, Adobe, "S," and Lancaster. Meticulously documented, Crossing Rio Pecos emerges as the definitive study of these gateways which were so vital to the opening of the western frontier.
