The Kamchatka Peninsula is a 1,250-kilometre (780 mi) peninsula in the Russian Far East, with an area of 472,300 km2 (182,400 sq mi). It lies between the Pacific Ocean to the east and the Sea of Okhotsk to the west. Immediately offshore along the Pacific coast of the peninsula runs the 10,500-metre (34,400 ft) deep Kuril-Kamchatka Trench.

This image focuses on the southermost part of the peninsula, which is blanketed with snow. Visible in the upper left quadrant is a massive shield volcano, the early Pleistocene Bolshaya Ipelka Volcano. Although extensively eroded by glaciers, it is the largest volcanic structure of southern Kamchatka. It has a large volcanic caldera surrounded by a ring-shaped ridge with steep inner walls and rocky outer slopes.
