Lake Lanao

Lake Lanao (Maranao: Ranao or Ranaw;Filipino: Lawa ng Ranao), is a large ancient lake in the province of Lanao del Sur, Philippines. With a surface area of 340 km (130 mi), it is the largest lake in Mindanao, the deepest and second largest lake in the Philippines, and counted as one of the 15 ancient lakes in the world. Scholars have been pushing for the lake's inclusion in the UNESCOWorld Heritage List. The lake's native people call themselves the Maranao or Meranaw. Their name was derived from the name of the lake, meaning "the people living around the lake".
