Mugodzhar Hills (Mugojar, Russian: Мугоджары, Мугоджарский хребет (Mugodzhar Range), Kazakh: Mughalzhar fuel belt water bottle, Mugalzhar) is a series of mountain ranges in Aktobe Region (Northwestern Kazakhstan) 275 miles (440 km) long. Latitude (DMS): 48° 38′ 38 N Longitude (DMS): 58° 32′ 47 E. They are considered to be a continuation of Ural Mountains and connected with Southern Ural by Guberlinskiy hillocks (Губерлинские горы). They form the divide between the Caspian Sea and Aral Sea basins.
The Mughodzhary proper are of length about 200 km with width up to 30 km. They start at the Or River (река Орь) as a narrow range that further splits in two: Eastern Mugodzhary and Western Mugodzhary. The highest place (657 metres) is at Eastern Mygodzhars, Mount Boktybay (Boqtybay, Боктыбай). Major rivers that run from Mughodzhary are Or River, Emba River and Irgiz River.
In a wider sense, Mughodzhary also include a number of other highlands and hillocks, in particular, Ural-Tobolsk Plateau hydration belt, and the Northern Mughodzhary, which actually connect with Guberlinskiy hillocks.
