The wide-ranging and shifting tides along the shoreline washed over and flattened the coastal dunes into horizontal layers called the Bell Rock Member of the Schnebly Hill Formation. Detailed mapping of this curious distribution revealed that lava was precluded from flowing to the north by the presence of partially eroded but high-standing red rock buttes or the Mogollon Rim. Output: LINESTRING (0 0, 1 1, 1 2, 1 1, 0 0). Other higher layers can be seen in the distance in the Mogollon Rim.
