Trou au Natron (French: "hole of natron") or Doon Orei (Teda: "big hole")[1] is a volcanic caldera of the Tibesti Massif in the nation of Chad in Northern Africa.[2][3] The volcano is extinct. It is unknown when it last erupted.[4][5] Its volcano number is 0205–01.[6] Trou au Natron is located just south-east of Toussidé, the westernmost volcano of the Tibesti Mountains. Its edge cuts into the nearby Yirrigue caldera.
