St. Croix, U.S. Virgin Islands, Caribbean Sea

STS054-74-049 (13-19 Jan. 1993) --- St. Croix is the largest, and most industrial of the U.S. Virgin Islands. This photograph captures St. Croix's features in great detail. The large industrial complex in the middle of the southern shore is the world's largest petroleum refinery. The main city, Christiansted, can be seen across the island on the north shore. The reefs around the eastern end of St. Croix are preserved as a submarine national park -- Buck Island Reef National Park -- around the small island off the north shore of the eastern end of St. Croix.
