Haystack Rock is a 235 ft sea stack in Cannon Beach, Oregon. It is sometimes claimed locally to be the third-tallest such intertidal structure in the world, but there are no official references to support this.
A popular tourist destination, the monolithic rock is adjacent to the beach and accessible by foot at low tide. The Haystack Rock tide pools are home to many intertidal animals, including starfish, sea anemones, crabs, chitons, limpets, and sea slugs. The rock is also a nesting site for many sea birds, including terns and puffins
Composed of basalt, Haystack Rock was formed by lava flows emanating from the Blue Mountains and Columbia basin about 15-16 million years ago. The lava flows created many of the Oregon coast’s natural features, including Tillamook Head, Arch Cape, and Saddle Mountain. Haystack Rock was once joined to the coastline but years of erosion have since separated the monolith from the coast. Three smaller, adjacent rock formations to the south of Haystack Rock are collectively called “The Needles”.
Haystack Rock was granted Marine Garden status by the Oregon Department of Fish and Wildlife in 1990. Collecting plants or animals is strictly prohibited. Climbing above the mean high tide level (barnacle line) disturbs nesting birds and is not allowed. The Haystack Rock Awareness Program is run by the City of Cannon Beach and conducts educational seminars at the rock during low tide between February and October.
