This 15-Million-Year-Old Monolith Stands Guard Over Oregon’s Most Beloved Beach and Marine Garden

Haystack Rock Tower

Rising 235 feet from the surf at Cannon Beach, Haystack Rock is Oregon’s most photographed chunk of coastline for good reason. The massive rock formation doubles as a protected wildlife refuge, hosting everything from nesting seabirds to colorful tide pools, all within walking distance of town.

The rock formed about 17 million years ago when lava from Eastern Oregon flowed all the way to the coast. Over time, the ocean wore away the softer rocks around it, leaving behind this massive chunk of hard basalt rock.

Now it’s protected as part of the Oregon Islands National Wildlife Refuge and the state has named it a Marine Garden.

This Sea Stack Is One of the World’s Biggest Rocks You Can Walk To

Haystack Rock stands out as one of the largest sea stacks that people can reach by walking along the beach at low tide. It’s as tall as a 23-story building and its base is wider than two football fields.

The rock got its unique shape from ancient lava that traveled miles away from Eastern Oregon. While you can only walk up to about 45 feet of its base during low tide, the rest of the rock stretches so high that you can see it from miles down the beach.

Tufted Puffins Make Their Nests at the Top

When spring arrives, Haystack Rock becomes home to Oregon’s biggest group of Tufted Puffins. These small seabirds look like flying penguins with bright orange beaks and white face patches, and they dig burrows into the grassy top of the rock to make their nests.

About 25 to 50 pairs of puffins come back each year until mid-summer. They share the rock with other seabirds like Common Murres, Pigeon Guillemots, and Western Gulls, and you can often spot them diving for fish or carrying several small fish at once in their beaks back to their nests.

Low Tide Reveals a Hidden Underwater World

When the tide goes out, you can explore one of Oregon’s most amazing tide pool areas right at the base of the rock. The pools are full of bright purple and orange sea stars, green anemones that close up like flowers if you touch them gently, and clusters of black mussels stuck tight to the rocks.

As you walk around the pools, you might see hermit crabs moving between them or spot colorful sea slugs called nudibranchs. Since this area is protected, all these sea creatures can live here safely without being disturbed.

The Distance to the Rock Changes With the Seasons

The rock stays put, but how far you have to walk to reach it changes throughout the year. In summer, gentle waves pile up sand on the beach, making it easier to walk to the rock’s base.

Winter is different – big storms can wash away up to 10 feet of sand, making the rock seem farther away. The weather changes how you experience the rock each time you visit, and during the biggest winter storms, waves crash against it and shoot up almost halfway to the top.

The Rock Is Actually the Core of an Ancient Volcano

Haystack Rock isn’t just any ordinary rock – it’s what’s left of an old volcano. It formed when hot liquid rock hardened inside a volcanic vent, while the softer rock around it slowly wore away over millions of years.

The rock is made of basalt that contains dense minerals like plagioclase and augite. These tough minerals are why the rock has lasted so long while everything around it disappeared.

The Rock Creates Its Own Weather Shield

The massive size of Haystack Rock blocks strong ocean winds, creating a calm spot on its east side. When coastal winds blow strong winds, you’ll find the temperature in this sheltered area can be warmer than the open beach.

This wind protection also helps the sea life around the rock. In the calmer water on the protected side, certain creatures like anemones and mussels can grow better than in other spots along the coast.

Native Americans Used to Fish Around the Rock

Long before tourists started visiting, the Tillamook and Clatsop tribes used the waters around Haystack Rock as a fishing spot. They found plenty of food here, including mussels, purple sea urchins, and different types of rockfish.

The tribes also used the rock to help them navigate along the coast. While you can’t fish right next to the rock anymore to protect the sea life, the surrounding waters are still home to fish like lingcod, cabezon, and black rockfish.

The Origin of Haystack Rock’s Name

Haystack Rock earned its name due to its shape, which resembles a haystack—a pile of hay before it’s baled. Its distinctive, rounded top and sloping sides, particularly when viewed from a distance, create this haystack-like appearance.

In addition, a U.S.G.S. report from 1980 reveals that the rock was once referred to as Inspiration Point, though the name Haystack Rock has since become more widely recognized.
