Abstract
The purpose of this paper is to present isopach maps of certain stratigraphic divisions of the Cretaceous system and structure-contour maps of certain horizons of that system in Nebraska. Tables of factual data also are included. The maps indicate clearly that certain structural "highs" such as the Chadron-Cambridge axis and the Sioux Falls "high," in conjunction with a large well defined basin across central Nebraska and another deep basin west of the Chadron-Cambridge axis, dominated the structural and depositional history of Nebraska during the Cretaceous period.
