Grand+Valley+1A

The Valley is eroding away every time weathering and erosion happens, making it jagged, inside the valley. Terrain is also the cause of erosion in the valley. The Grand Valley is still beautiful, even though it’s eroding and weathering is tearing it a part.

Before the Grand Valley oceans and deserts covered Western Colorado which left good deposits like sand which compressed into sandstone and ended up forming into a protective layer that had kind of hard basalt and left with a hundred feet deep.
