When the tide is high, the Pacific Ocean seems to sink into a circular hole on the coast of Oregon, at the Cape Perpetua promontory. It looks like an opening in the ocean capable of sucking water to the center of the Earth, so much so that someone called it The drainpipe of the Pacific. While others have found more suggestive names, such as the gate to hell and Thor’s Well. And it is under the latter name that this curious rock formation on the West Coast of the United States is most commonly known.
