Tillamook Head is a high promontory on the Pacific coast of northwest Oregon. It is located about 5 miles (8 km) southwest of Seaside. The promontory forms a steep rocky bluff on the ocean, approximately 1,200 feet (366 m) high, located in Ecola State Park.
The headland is a tilted remnant of a 15-million-year-old Columbia River basalt flow. The lava welled up near modern-day Idaho, and flowed down the Columbia Gorge. It spread along the Oregon Coast to Tillamook Head, eventually cooling to form a 600-foot thick basalt sill.
The promontory is named after the Tillamook people, a Salishan-speaking tribe of Native Americans that inhabited the coast. An archeological site associated with the Tillamook people, is located near Cannon Beach. Several ground depressions at the site have been interpreted as house pits, possibly indicating the presence of a village site occupied from about 1100-1700 CE. In 1806, Captain William Clark and 12 members of the Corps of Discovery journeyed south from their winter encampment at Fort Clatsop, hiking over the promontory where they encountered a beached whale. Today, the park features miles of hiking trails through old growth forest and several beaches. Read more here and here.
