Ingedei
The Ingedei, or Ingoda, flows through the wooded highlands of Transbaikalia. Its upper course runs below the Khentii Mountains, and farther east it joins the Onon to form the Shilka, a headstream of the Amur. The long river valley cuts through a landscape of mountain ranges and forests. Winter grips the water for much of the year, with the river normally frozen from early November until late April.
