The Rio Grande serves as the focal point of this 1971 study, defining the international boundary between Texas and Mexico. The landscape is dominated by a complex network of dry drainage systems, including Colorado Canyon, Closed Canyon, and Tapado Canyon, which carve through the high ground towards the river. A small Cem and a lone Jeep Trail represent the sparse human footprint in this border region during the early 1970s.
