Sea Stacks

Sea stacks are tall, isolated rock formations that stand alone in the ocean near the coastline. They form over thousands of years through the process of erosion, where waves, wind, and weather gradually wear away the softer parts of cliffs or headlands. As the surrounding material erodes, harder rock remains, creating these striking columns or pinnacles. Sea stacks are often scenic and serve as natural landmarks. They highlight the dynamic interaction between land and sea and are commonly found in coastal regions with rugged cliffs, such as the iconic stacks off the coast of Ireland, Australia, and the United States.
