Oktyabr'skii Coast
On Kamchatka's western coast a sandspit separates the mouth of the Bolshaya River from the Sea of Okhotsk. Salmon ascend the river to spawn; the Bolshaya was also a route across the peninsula toward the Kamchatka valley and eastern shore. The Itelmen communities of Kamchatka relied heavily on fishing, using nets and river weirs to catch the seasonal runs.
