Petelka 1948 Sept. 3 Prisoner Harbor, Santa Cruz I. repeatedly were noted near camp. Barn Swallows have been noted daily; a group of 5 or 6 was present up canyon this morning. Sept. 4 5½ mi W Stanton Ranch Rdgtrs., 1908 ft., Santa Cruz I. Last mile Pearson and I drove up to the ridge at the head of the W-facing canyon above Christop Ranch, where occur the only good stands of Santa Cruz Island pines that we have seen thus far. The area is one of rather spectacular beauty, there being several large canyon drainages visible from the ridge, also the ocean to the south and west, and Santa Rosa Island beyond. To the north of our location is seen Devil's Peak; to the south a broad canyon drainage leading to Johnsons, with a good area of shrub and trees on a NW-facing slope, opposite our location, with ironwood standing out conspicuously in the draws or on slopes where they received cool updrafts; to the SW is another sharp peak, without a name so far as we know; to the west and east are broad canyons along the main fault of the island. In that to the west, the pines grow on the N-facing slopes and form a forest very similar to the type formed by Monterey pine. The trees were relatively young, as so it seemed from the fact that most of the trunks ran about 4-8 inches in diameter with the trees rather closely set. Associated with the pines were several species of oak, (one Q. agrifolia), Photinia, Comarostaphylos, Vaccinium ovatun, Diplacus (common), manzanita, and Sumac. of [illegible] Young growth of apparently stump sprouting species,
