Hogbacks
Hogbacks get their name because
they look like the topside of a razor back hog (see picture on main page).
When rocks are uplifted by mountain building processes, erosion of the
softer, less resistant rock occurs leaving a ridge of the more resistant
rock. At one time this area was flat, then uplifting occurred. From
the picture above you can see how one side of the ridge is older then the
other because of the laws of original horizontality and superposition.
