The Udina volcanic massif consists of two cones constructed along a WNW-ESE line at the south end of the Klyuchevskaya volcanic group, and SE of Tolbachik. The western cone is Bolshaya Udina, seen here from the south, and has a lava dome on the SW flank. The smaller Malaya Udina is out of view to the right.
