The Gizeldon River, also Gizel' don, is a river and valley of North Ossetia–Alania in southwestern Russia. It is a tributary of the Terek River.[1] It flows for 81 kilometres. A valley with many cliffs and a 4000 metre peak,[2] the area is prone to avalanches; 30 were reported in 1967-1968.[3] The terrain is described as having "craggy, gashed terrain", with cattle breeding, lumbering, and lead-zinc mining being the principal economic pursuits of the people of the Gizeldon valley.[4] A hydroelectric plant has been built on the Gizeldon River.
