Eastern, KY Sandstone

This is a piece of sandstone I picked up in Eastern Kentucky near Red River Gorge (but not in the park). I loved the layering and it makes me wonder what event took place to produce the contrasting layer. I just wish I could tell which side was the top. I assume, because of the prominent red sandstone in the area, the black deposition is out of the ordinary. I just don't know if this piece represents a normal red sandstone layer with the disturbance on top or if I am witnessing a past disturbance with the return of the regular deposition. Could it have been an earthquake, a forest fire, land or rock slide or a flood? Either way, it tells some story of Eastern, KY and it's pretty cool.
