Thor’s Well Fun Fact: Thor’s Well, also known as the “Drainpipe of the Pacific,” is an optical illusion! While it appears to be a bottomless pit sucking in seawater, Thor’s Well is actually only about 20 feet deep. It’s a collapsed sea cave, and during high tide, waves crash into it from below, creating dramatic, fountain-like bursts of water that give it the appearance of endlessly draining the ocean.
