lines running across the island. The island is comprised of 162 acres and rises to an elevation of 186 feet above sealevel. The island is a part of the Water Island Formation that was lain down in the Lower Cretaceous. The northern tip is tonalite, gabbro and granite from the tertiary period, the north western tip as wel
ne flats, saline marshes and salt ponds. The soils are very deep and poorly drained, strongly saline and frequently ponded for very long periods. Southgate-Rock outcrop complex (SrE), 20 to 40 percent slopes is found on the summits and side slopes of volcanic hills and mountains. It has a surface layer of 0
miles. The oldest rocks of St. John are submarine lavas (keratophyre and spilite), beds of volcanic debris and chert. Associated intrusive rocks of the Water Island Formation is overlain by andesitic volcanic and volcanoclastic rocks of the Louisenhoj Formation which underlies the island of St. Thomas to the east and muc
