The Thickness of the Drift in North Dakota with Refrence to the Bedrock Formation

<p>Glacial drift covers the major portion of North Dakota. The drift ranges in thickness from 0 feet to approximately 500 feet, and averages 200 feet. In some areas the drift is conformable to topographic features, however, in other areas where the surface of the bedrock has eroded valleys the drift is relatively thick without showing any change in altitude of the topography. In general, the drift thickness appears to vary with the physiographic divisions of the state. </p><p> The contoured thickness of the drift is based on drilling data which is plotted on an isopachous map. Due to lack of drilling in certain areas, information is scarce as to drift thickness. If sufficient data were available the thickness of the drift would probably display a varied pattern of thicker and thinner isolated localities, because of uneven surface of the bedrock formations and the varied types of glacial deposits mantling the State. The ground water, clay, sand, and gravel deposits found in the glacial drift are of economic importance to the State. </p>
