Progressive Overlap of Shore
Natural and columnar sections at each end and at the center of a line 100 miles long and at right angles to the original trend of the shore. The progressive overlap and change in facies is shown. Note that in each section the clastic formation next above the crystallines is a sandstone, but that it belongs to different formations in each.
