Oregon Coast Quiz – Haystack Rock, Sea Stacks and Tide Pools

The Oregon coast is famous for sea stacks, rocky towers left as waves eroded ancient lava flows. Haystack Rock at Cannon Beach, a basalt stack about 72 meters high, hosts nesting tufted puffins and rich tide pools.

Oregon's 1967 Beach Bill kept ocean beaches open to the public. Highlights include Thor's Well near Cape Perpetua, the Heceta Head lighthouse, Sea Lion Caves with Steller sea lions and Bandon's Face Rock.

The Oregon Dunes helped inspire Frank Herbert's novel Dune, and The Goonies was filmed in Astoria and Cannon Beach. US Route 101 links most of the coast.
