The Gizeldon (Russian:Гизельдон or Гизель-Дон; Iron Ossetic:Джызæлдон, Džyzældon), is a river in North Ossetia–Alania just west of Vladikavkaz. It drains the northern slopes and glaciers of Mount Kazbek north to the Terek. The river is 80 kilometres (50mi) long, with a drainage basin of 604 square kilometres (233mi2). A valley with many cliffs and a 4000-metre peak, the area is prone to avalanches; 30 were reported in 1967–1968. 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. A hydroelectric plant has been built on the Gizeldon.
