In 1998, mysterious holes were discovered off the coast of California. Recent studies suggest that these holes were formed by sediment gravity flows, eroding the centers of the holes over time. No methane was found in the area, contrary to previous beliefs. The Sur Pockmark Field contains over 5,200 depressions and is located off the coast of Big Sur, California.
