Kantharalak District

Kantharalak (, ) is a district ("amphoe") in the southeastern part of Sisaket Province, northeastern Thailand.
History.
The old name of "Kantharalak" was "Mueang Uthumphon Phisai", controlled by Mueang Khukhan. The central office was in Ban Kan Tuat, Tambon Uthumphon Phisai (not to be confused with latter-day Uthumphon Phisai District.) The present district office is in Tambon Nam Om.
In 1939 the district name was changed from "Nam Om" to "Kantharalak".
Etymology.
The name "Kantharalak" means 'countless ravines', from Pali "kandara" ('ravine') and the Sanskrit "lakṣa" (लक्ष), 'a hundred thousand'.
