Two maps of the Venera 10 landing site. At left a context map shows bright and dark areas, the bright parts being a hilly area cut by many faults and the dark areas being smoother surfaces probably covered with sediments. A mountain in the south part of the map is a volcano, and flows extend from it to the north and east. Venera 10 could have landed anywhere in a 300 km diameter circle filling much of the map. At right the central part of that landing region is shown in more detail revealing plains cut by ridges and fractures, and part of the hilly area.
