Sea Stacks and Coastal Geology

The video explores the geology of Olympic National Park, focusing on sea stacks at Ruby Beach. It explains how sea stacks form through preferential erosion and discusses their global presence and significance. The video also highlights the dangers of sea stacks, including shipwrecks, and concludes with acknowledgments to Subaru for their support.
