Eight hundred feet southeast of the mouth of Baldwin creek, at 29, a 3 to 6 inch dike of hard, brown, rather fine grained sandstone is exposed with a dip of 80 degrees north, 75 degrees west. It cuts the shale to the top of the cliff, and, owing to its hardness, pro- jects several feet from the side of the cliff at one place, as shown in figure 11. A freshl}^ broken piece of this sandstone gave no odor of bitumen. An interesting intrusion of the Santa Cruz region is that of dike 30, a few hundred feet west of the mouth of Baldwin creek, and.
