A striking depiction, using full hachure shading to dramatize the steepness of these islands in the Santa Barbara Channel. Includes elevation view of the eastern extremity of the island with arch rock still intact. Although titled a "Preliminary Survey," this chart has extensive and detailed topographic detail along with numerous soundings.
Fine, clean example with one small spot.
