more regular arrangement than those quoted above. Much of the material is silty 

 clay and fine sand. Laminated structure is common, the thin laminae extending 

 for several hundred feet, but invariably replaced sooner or later by sediments of 

 different texture or composition. When long sections are exposed so that they can 

 be seen ensemble, it is noticeable that the beds undulate. Strictly speaking, there 

 is no horizontality of beds, but rather a slow rise and fall. Long, flat augen of 

 sand are the apparent cause of this arrangement. These flat lenses occur fre- 

 quently, the finer sediments wrap them about, and the bedding of the latter is 

 made to show corresponding undulations. The degree of undulation is determined 

 by the thickness and length of the sand lenses.
