Small-scale structures, including ripple marks, slump marks of two types, and rain patches, occur locally on the surfaces of steeply dipping laminae in the eolian Coconino sandstone. These surface features are described and analyzed. Comparisons are made between them and similar structures observed in the modern dunes of the Navajo country. Most of these structures were reproduced experimentally in a wind tunnel and sand box, where controlled conditions made possible a determination of factors involved.
