Pacific Ocean - Oregon
 
Sea stacks, islands, and the rocky shore, were formed by millions of years old lava flows originating from present day Eastern Oregon and Washington. The flows cooled into solid basalt and millions of years of erosion have resulted in the natural wonders we see today.
At sea level, rocks in the intertidal zone are covered with unique creatures that have adapted to survive in this turbulent environment, most of the time under the water, but often left high and dry for hours
