escarpment or scarp, long cliff, bluff, or steep slope, caused usually by geologic faulting (see fault) or by erosion of tilted rock layers. An example of a fault scarp is the north face of the San Jacinto Mts. in California. Examples of erosional escarpments include the Palisades along the Hudson River and the long break separating the coastal region from the inland area in Texas, roughly paralleling the coast.
