East Europe as a proto-homeland of the Indo-Europeans. S. V. Zharnikova

of the Bolshezemelskaya tundra is the so-called Zemlyanoy or Bolshezemelsky ridge, stretching in the latitudinal direction from the Pechora River to the junction of the Urals with Pai-Hoi and serving as a watershed between rivers flowing south and flowing into latitudinal sections Mustache and Pechora rivers, and rivers that carry their waters in the Barents Sea. Recently, some researchers have denied the existence of such a ridge as an orographic whole,» – the authors of «Geology of the USSR» write. But they also note that: «This question is still not entirely clear, it is not clear how the Nenets, who know the terrain perfectly, could assign a single name to the hill, which in reality is not in nature. In any case, a chain of discontinuous hills with an almost latitudinal orientation is well traced on the watershed of the Shapkina and Chernaya rivers, where in places they reach 250 m in height, and between the rivers Kelva-vis and Hoseda-yu, where Verga Musur rises to 175 m.»
