Two small basaltic scoria cones seen here from teh SE are part of the Jombolok lava field, about 200 km WNW of the SW tip of Lake Baikal. The eroded cone to the lower right is Stariy. The young cone (near the center) is Peretolchin, named after a geologist who disappeared in the early 20th century, prior to the Russian revolution. This was the source of the voluminous 75-km-long Jombolok lava flow.
