Cannon Beach from the an ancient Volcanic Rocks

Haystack Rock in Cannon Beach is a 235-foot-tall basalt monolith that was formed roughly 15 to 17 million years ago. It was created when massive lava flows from the Yellowstone Hotspot traveled along the Columbia River drainage system and intruded into the soft marine sediments of the ancient sea floor. Over millions of years, geologic uplift and erosion wore away the softer surrounding sediments, leaving behind the hard volcanic rock we see today. Today, it stands as one of Oregon's most iconic landmarks and a protected Marine Garden.
