"If you can find my pictures for this location from a year ago, the change is enormous! I picked the spot because of the huge slide and the lone tree looking precarious at the top of the bluff. Today most of last year’s slide material is gone and the tree is on the beach - root ball first. This spot is about 3/4 of a mile north of Lagoon Point’s north parking lot. The entire bluff from there to here has changed since last summer. It is so dramatic it is worth a visit!"
