COAST RECORDS OF THE RISE OR FALL OF LAND 249 



The upraised cliff. Upon the coast of southern California 

 may be found all the features of wave-cut shores now in perfect 

 preservation, and in some cases as much as fifteen hundred feet 

 above the level of the sea. These features are monuments to the 

 grandest of earthquake disturbances which in recent time have 

 visited the region (Fig. 274). Quite as striking an example of 

 similar movements is afforded by notched cliffs in hard limestone 

 upon the shore of the Island of Celebes (Fig. 275) . But the coast 

 of California furnishes the other characteristic coast features in the 

 high sea arch and the stack as additional monuments to the recent

uplift. Let one but imagine the stacks which now form the Seal 

 Rocks off the Cliff House at San Francisco to be suddenly raised 

 high above the sea, and the forms which they would then present 

 would differ but little from those which are shown, in Fig. 276. 



The uplifted barrier beach. Within the reentrants of the 

 shore, the wave-cut cliff is, as we know, replaced by the barrier 

 beach, which takes its course across the entrance to a bay. After 

 an uplift, such a barrier composed of sand or shingle should be 

 connected with the headlands, often with a partially filled lagoon 

 behind it. Its cross section should be steep in the direction of 

 the lagoon, but quite gradual in front (Fig. 277).
