The Polar region of the Urals has become a glacial landscape over the past few hundred thousand years. The glacial movement of the polar region can be seen through large deposits of glacial till and erratic stones. The large cirques of these frozen mountains contain large glaciers. Large arête’s can be seen in the polar Urals, the arêtes were created when multiple glacial forms created adjacent cirques and parabola valleys; this leaves a sharp rock edge. Many large glacial lakes are represented in the polar landscapes of the north; the large lakes were created by retreated glaciers of millions of years ago.

The southern portion of the Urals, specifically the western slope has large Karst regions riddled with large dolines (sink-holes, underground rivers). This ancient mountain range used to have coastal regions millions of years ago creating large areas of sandstone and limestone.
The southwest region is primarily sedimentary limestone and dolomite and allows for chemical weathering of the rock. Thousands and thousands of years of weathering created large caves throughout the region. These large caves are created from underground streams that carve out large sections of the sedimentary rock. Much of the rivers in this region have dissolved loads filled with limestone sediments.
