Description
Erosion of weathered rock material is an important landscape forming process, but along many parts of the trails volcanism and mountain building have occured so recently they are the dominant factors in landscape formation. However, between Ash Hollow and Scotts Bluff, rapid erosion of the soft sedimentary layers is responsible for the landforms that so many emigrants described.
