OUTWASH PLAINS. The large quantities of water that flowed from the melting ice deposited various kinds of materials, the most important of which is called glacial outwash. Outwash plains made up of outwash deposits are characteristically flat and consist of layers of sand and other fine sediments. till plain is composed of unsorted material (till) of all sizes with much clay, an outwash plain is mainly stratified (layered and sorted) gravel and sand. The till plain has a gently undulating to hilly surface; the outwash is flat or very gently undulating where it is a thin veneer on the underlying till.
It is straight and narrow like the handle of a pan with the broader area of the state below it, like the bottom of a pan. This region has mostly flat, grassy land or plains. These plains are part of the same flat grassland that extends from the Great Plains of the Central United States. Sometimes this land is also called the Llano Estacado or âStaked Plains.â The land is mostly treeless and is on a high, flat plateau. The eastern part of the Panhandle is not quite as flat. It is lower in elevation and called a rolling plain. There is more rainfall in this eastern half and it is brushy.
