Not illustrated. 1858 Excerpt: ...very tough, so that the rock can be broken out in blocks. It is very light and porous, absorbing water rapidly when wet, and emitting a strong argillaceous odor. It is principally white clay and fine sand, and does not effervesce with acids. It appeared to have been quarried, under the supposition that it contained lime. At San Pedro, twenty miles distant, there is a fine exposure of the edges of strata in the bluff overhanging the beach. This bluff is from forty to sixty feet high, and is nearly vertical, being constantly undermined by the waves. The strata appear in nearly horizontal lines along the face of the bluff, and present a considerable difference in their lithological characters. Some of them are almost wholly formed of clay, others of soft sandstone, and others of a more compact, but fine-grained rock, formed by the mingling of the two materials. With the exception of some beds at the base of the series, they are all light-colored, and have a modern appearance. The lower beds are bituminous, and emit a strong odor of bitumen when they are struck by the hammer. This bituminous mass is thinly stratified, and is, in fact, a mass of bituminous, clay shales, which are soft and plastic where washed by the tide. They are exposed along the shore, the base of the beds being below the surface of the water, but the upper limit rising in places to a height of five feet above it. Above these bituminous shales the argillaceous beds are stained with oxide of iron, and nodular masses or concretions of the oxide protrude from the face of the bluff at many points. A short distance beyond the landing, the upper part of the beach, under the cliff, is strewn with large, tabular blocks of sandstone, of a brown color, and evidently derived from the wear of the bank.
