Starting at the eastern foot of the Rocky Mountains in the midwest United States, the dramatic landscape of the High Plains stretches across several US states.

Plain, any relatively level area of the Earth’s surface exhibiting gentle slopes and small local relief.

Plains vary widely in size. Extensive stream-laid sand and gravel deposits, which contain the Ogallala aquifer, underlie the plains.

It is characterized by a constructional topography formed on thick deposits of wind-blown materials that blanket the region. : 355. The High Plains are a subregion of the Great Plains mostly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. Generalized Geology and Hydrogeology. Windblown sands and silts form thick, rich soils and caliche locally. Figure 6. Geography and climate. Darwin Spearing writes in Roadside Geology of Texas: The 'Staked Plains' tale is deeply entrenched in Texas mythology, but the real interpretation of Llano Estacado is sensible geologic: it means 'stockaded' or 'palisaded' plains - which is precisely how the edge of the plains appear when viewed from below the caprock. Generalized geologic units that compose (blue shading) and underlie (gray shading) the High Plains aquifer (Modified from Gutentag and others, 1984).

HIGH PLAINS.The High Plains region, the northern and western side of Texas from the Panhandle to the Pecos River, is physiographically a quadrangular, mesa-like area that rises perceptibly by sharp escarpments above the adjacent lowlands to the east and to the west. Source: Google Earth / Landsat / Copernicus . (Click image for larger version). The High Plains of Texas form a nearly flat plateau with an average elevation approximating 3,000 feet. High Plains.

In the Panhandle of Texas – here an area near Silverton – one can witness how the High Plains, dotted with lakes, gradually erode at the edges. The smallest occupy only a few hectares, whereas the largest cover hundreds of thousands of square kilometres—as, for example, the Great Plains of North America and Overview of High Plains/ North-Central Texas Geology Palo Duro Canyon This geologic area transitions from the gently sloping gulf-coast plain to the diverse types of rock formations ranging from Paleozoic to Cenozoic found in the High Plains Palo Duro Canyon was formed by the Red
