The folding of layers of sedimentary rocks with thicknesses of a whole lot of metres to a couple kilometres usually leaves lengthy parallel ridges and valleys termed fold belts , as, for example, within the Valley and Ridge province of Pennsylvania within the jap United States.

Excessive above towering Douglas firs, breathtaking views of town of Vancouver, sparkling Pacific Ocean, Gulf Islands, and snowy peaks unfold as you journey up the mountainside.
An extended par 4 playing along the mountains. Folds of this sort have shaped at depths the place the rocks had been sizzling and gentle before they reached the relatively cold floor of the Earth.
