Evolutionary Story: |

|
|
“The Appalachian Basin was
formed about 360 million years ago. Through time, sediments were carried by
rivers from the east to a shallow sea which covered most of the continent to
the west. These sediments became layers of sandstone, shale and siltstone. |

“At
the end of the Paleozoic Era, 245 million years ago, the tectonic plates of the
earth’s crust began colliding and the upper layers were folded and faulted
into a high, rugged mountain range. “Erosion has reduced these
once towering mountains to what we see today. Can you see Sideling Hill?” Summary: One layer was laid down over a long period of time, and then hardened; another layer was laid down over that one grain at a time, then it hardened and the next layer started to build. After that, two continents collided and formed two gigantic mountains, then rain eroded the two mountains away and left the valley standing as the mountain we now call Sideling Hill. |

Young Earth Theory: |

The other theory is that the layers were laid down horizontally, very quickly during a world-wide flood about 4-5 thousand years ago. While these layers were still flexible, in their “plastic” state, they were bent and the mountain range pushed up while still submerged under water into the formation we see today. |
