The Volga Upland is a large upland within the Russian Plain, whose southern and central parts encompass the lands of the Volga region. Nizhny Novgorod Oblast borders it in the southwest: this is where the northern tip of the upland lies, containing a number of notable natural features of the region.
Relief and geology
The northern tip of the Volga Upland within Nizhny Novgorod Oblast is represented by a plateau-like erosional terrain with absolute surface elevations of 130–210 m. High riverside chains of outlier ridges rise 100–150 m above the Oka. Bedrock Permian formations — clays, sandstones, marls, limestones, gypsum — are overlain by a thin mantle of loose loams and sands, in places by till, and by Jurassic and Cretaceous clays. The plateau is dissected by ravines, gullies, and broad valleys of small rivers; karst landforms — caves and sinkholes — are common.
Rivers of the upland
The Sura River — a right tributary of the Volga and one of the most picturesque rivers of the region — rises on the Volga Upland. The Sura flows through Nizhny Novgorod Oblast and a number of other Russian regions, discharging into the Cheboksary Reservoir.
Protected areas
The Peremilovskiye Hills are associated with the northern tip of the Volga Upland — a natural feature in Nizhny Novgorod Oblast notable for its diversity of flora and fauna, including species listed in the Red Data Book.
