Dept. of Geology and Mineral Industries Bold, rocky headlands alternating with long curved beaches, sand spits, and bays -- these are the dominant landforms that make up the more than 40 miles of scenic coastline between Roads End and Tillamook Bay. With the exception of Cape Kiwanda, which is composed of sandstone, the headlands are made of basalt, a rock that erodes slowly. The lowlands and bays between the headlands are in more easily eroded sedimentary rock. Thus the coastline is scalloped by a sequence of large protrusions and indentations. Viewed in detail, however, there are numerous small shoreline features such as points, knobs, coves, and sea stacks that are due to local variations in bedrock characteristics.
