Bolshoy Kekuknaysky (Russian: Большой Кекукнайский) is a volcano located in the central part of the Kamchatka Peninsula, Russia. It comprises two shield volcanoes: Bolshoy (1301 m) and Kekuknaysky (1401 m).[1] Their lava flows and cinder cones have dammed a valley dissecting the mountain, creating the Bolshoye Goltsovoye and Maloye Goltsovoe lakes. The last eruption occurred at Kekuk Crater, about 7,200 years ago.
