The photo above shows uplifted marine terraces (late Quaternary); this view looking toward the northeast from Trinidad Head, California. Terraces define one limb of a broad anticline related to transpression (the simultaneous occurrence of strike-slip faulting and compression of the Earth's crust), near the northern end of the San Andreas fault system. Note both modern and ancient sea-stacks (modern at left in the middle distance and ancient at left-center in the far distance).
