Summary Author: Marli Miller

Sea stacks mark former positions of the coastline, but remain standing above the waves because they are more resistant to erosion. At Bandon Beach, these sea stacks consist of sandstone, greenstone, chert, and even blueschist blocks. These rocks belong to the Jurassic age Otter Point Formation, a part of the Franciscan Assemblage that was accreted to the west coast of North America during the Cretaceous.
