12-30-07 ISLA SAN JOSE: A great morning hike up an arroyo through high walls of conglomerate dotted with lots of granite boulders and cobbles. The conglomerate deposits were re-eroded by the present stream as the island was uplifted. The meanders of the watercourse have created a dramatic maze. The vegetation growth is heavier in the arroyo than on top of the canyon. We climbed up the sidewall of the arroyo over a steep, eroding surface to the top of the island for views large crater-like alluvial plain on the other side. Lily brushed a cholla cactus on the way down and was quite unhappy about it.

ISLA SAN FRANCISCO: Half Moon Bay is a beautiful crescentic beach a mile across. We snorkeled along one limb of the arc off a rocky headland. There were millions of fish, mostly anchovies, in clear, very cold water. The crew set on a BBQ on beach for dinner complete with a fire and marshmallows. When we got back to the ship, a dozen pelicans were feeding near the ship in the water light up by the ship’s lights.
