  Haystack Rock, Clatsop County, Oregon
Photograph taken 17 Sept 2009.

Haystack Rock is a 235-foot (72-meter) tall monolith (or sea stack) on the Oregon coast in the northwestern United States, the third-tallest such "intertidal" meaning it can be reached by land, structure in the world. A popular tourist destination, the rock is adjacent to the beach and accessible by foot during low tide. Haystack Rock tide pools are home to many intertidal animals, including starfish, anemone, crabs, chitons, limpets, and sea slugs. The rock is also a refuge for many sea birds, including terns and puffins.

Composed of basalt, Haystack Rock was formed by lava flows emanating from the Grand Ronde Mountains 10 to 17 million years ago.
