Ozero Tyulen'ye

Tyulenye Ozero lies on the Bering Sea side of the Olyutor Peninsula, among bays and lagoons cut into the Koryak coast. Coastal cliffs expose layers of ancient volcanic rock, jasper and thinly bedded chert near the lagoon. Farther south, Cape Olyutorsky marks the peninsula's end and the eastern entrance to Olyutor Gulf.
