The Diomede Islands (65°46'N., 169°00'W.), consisting of two steep to islands in the middle of the Bering Strait, rise abruptly from the sea with nearly vertical sides. Their summits appear as broken tableland. Ostrov Rat manova (Big Diomede Island) (65°48'N., 169°05'W.), the W and larger of the two, is fringed on its W side by above water rocks. Little Diomede Island, about 2.5 miles SE of Ostrov Ratmanova, has a sandspit extending from about the middle of the W side of the island, and from the outer end of this spit a reef extends an unknown distance toward the S extremity of Ostrov Ratmanova.
