a V shaped valley cut by glacial melt water, reveals shales and sandstones laid down some 300 anticline-425x215million years ago when this part of the earths crust was close to the equator. Shales are formed from fine mud particles deposited as horizontal layers in quiet water conditions.

However, at one site a fold in the shales is clear evidence of later lateral compressional forces.

The shale beds in some sites contain both fresh water and marine fossils so there were also periods of sea incursion.

Such deposits are only transported by very fast flowing rivers. The bedding planes define the direction of flow, the sediments being derived from the erosion of mountain range to the north.
