Ostrov Brat Chirpoyev (Minami Jima), separated from Ostrov Chirpoy by Proliv Snou, a deep passage, rises to a conical summit near its W side. Mys Semenova (46°27'N., 150°51'E.) is the SE extremity of Ostrov Brat Chirpoyev. The headland is 33m high, and from it the land slopes gently upward. In summer, it is usually enveloped in fog. Rakko Jima, a steep, conical islet, lies close NE of the island. A reef, with some above-water rocks, extends about 0.3 mile E of this islet, and a rock, which dries 0.9m, lies about 0.5 mile SE of the islet. Skala Lev, a rock, lying close inshore, W of the summit of Ostrov Brat Chirpoyev, resembles a lion lying down, near which tide rips and eddies occur.
