The Kulaman Plateau referred to in archaeological studies comprises the present-day Senator Ninoy Aquino and some adjacent villages northeast of the municipality. The area is estimated to be about one thousand meters above sea level. Around Sultan Kudarat, however, Kulaman is more commonly described as a valley than as a plateau.
