parallel, almost latitudinally extending ridges in the Caspian Lowland, between the mouths of the Kuma and the Emba rivers. Their height is mostly from 10 to 45 m, and they are up to 25 km long. They are 200-300 m wide, with an average distance between ridges of 1-2 km.
The Baer Hills are made up of sand and fine rounded splinters of dense brown clays and compacted by a clayey substance. There are several hypotheses about the origin of the hills. Apparently the most likely is that they are windformed. The relief of the Baer Hills is very similar to the crests of Western Siberia and sandy desert ridges. They are named after K. M. Baer, who first described them.
