A large unnamed area of Holocene basalts and a possible small cinder cone is located on the floor of the Ethiopian Rift Valley SW of Tullu Moje volcano. The flows occupy a NE-SW-trending zone near the active eastern margin of the rift valley, E of Lake Ziway and NW of the massive Pleistocene Ch'llalo (Cilallo) volcano, one of the largest edifices of the central Ethiopian Rift Valley.
