Obbusen
This peninsula has a few arms or subpeninsulas extending northwards into the Kara Sea, where there are some large islands off its shores, including Oleniy, Shokalsky and Vilkitsky Islands. There are two bays in its northern coast, narrow and deep Khalmyer Bay and smaller Yuratski Bay. The peninsula formed between the Khalmyer Bay and neighbouring Yuratski Bay is known as the Mamonta Peninsula (; "Poluostrov Mamonta", meaning 'Mammoth Peninsula') and the narrow peninsula in the NW formed between this bay and the neighbouring Gulf of Ob is known as the Yavay Peninsula (; "Poluostrov Yavay").
