Dakota sandstone.

The Dakota Sandstone records the alternating rise (shale) and fall (sandstones) of sea level as the shoreline moved back and forth across the area~ 98 to 100 million years ago. Gradual, long-term rise in sea level deposited rocks of the Graneros Shale of the Mancos Group, a mud deposited on a shallow ocean floor about 98 million years ago.

Transgression occurs when the shoreline moves seaward, while regression occurs when the shoreline moves landward.
