Abstract

The High Plains of Texas occupy an area of about 35,000 square miles, extending from the northern boundary of the Panhandle southward about 300 miles, and from the New Mexico line eastward an average distance of about 120 miles. This region is divided into two segments by the Canadian River and the name Llano Estacado has usually been assigned by geologists to the southern, or larger part, which is bounded on the east and on the west by the escarpments of the High Plains and on the north by the valley of the deeply entrenched Canadian River. The ground water occurs chiefly in the beds of sand in the Ogallala formation, which underlies the surface throughout almost the entire region and in many places is 200 to 300 feet thick. It rests on an uneven floor of older rocks, which are exposed at the base of the escarpments bounding the High Plains and in the Canadian "River Valley. If water is found in them it is generally highly mineralized. As the water-bearing sands of the Ogallala are cut off in all directions by escarpments, they have no underground connections with water-bearing beds outside of the area except through the underlying older rocks, which contain highly mineralized water and could not be the source of the fresh water in the Ogallala. The source of this fresh water, therefore, must be the rain and snow that fall on the surface of the High Plains.
