Queen Valley
Ryan Mountain - Queen Valley
Queen Valley, a mountain-rimmed valley at an elevation of 4,450 feet is one of two types of valleys along the geology tour. The Queen Valley are formed by a difference in the rate of erosion between the rock material on the valley floor and the rock making up the surrounding mountains.
The valley material disintegrates more rapidly than the mountain rock, and forms a low-lying plain, or valley. The rocky mountain sides are more resistant to erosional forces, such as wind and water, and maintain their height as the valley becomes deeper. Pleasant Valley, seen later in the tour, is the result of faulting uplift and subsidence, another type of valley carving.
