BOTH THE PACIFIC AND ATLANTIC OCEANS possess their respective “Sacred Cross Island”: to the West, Santa Cruz of the California Channel Islands; to the East, St. Croix of the U.S. Virgin Islands. On 11-17-2018 I found myself swimming the waters off the North side of Santa Cruz Island. It was a spur-the-moment trip involving a few family members and the 15 ft Boston Whaler. It didn’t occur to me or anyone else that some of us would be, as already planned, in one weeks time swimming in the waters around another island whose name also means “sacred cross”. This “coincidence” was one that none of us consciously planned, and one which I didn’t pick up on until several days before taking off to St. Croix. Now after having been baptized by the waters of both crosses (two lines make a cross–X marks the spot), I can say the most critical experiential difference between the two is temperature: the Pacific version being a nippy 62 F; the Atlantic a paradisaical 82 F. Out of one you emerge with blue lips; the other, possibly sunburn. Below are photos of the underwater environments of both, grouped in twos: the first image from Santa Cruz, the second from St. Croix.
