Borawli stratovolcano is located E of Lake Giulietti (also known as Lake Afrera). The upper part of the volcano, seen here from the NW, consists of trachytic lava flows overlying basaltic flows. Young obsidian domes south of the volcano are the likely source of rounded pumice fragments found around the lake.
