Fault Scarp
Measuring the Rise of the Range
A fault scarp provides visual evidence of displacement of adjoining blocks of the earth's crust along a fault. near the base of Rockchuck Peak, the scarp shows nearly 60 feet of movement, mostly in the down-dropping of the valley. This movement generated earthquakes of the highest magnitude.Geologists estimate that displacement will continue as it has for the last nine million years. Through periodic earthquake-producing jolts, the mountains will hinge upward and the valley will tilt downward.
