Researchers of the northern and alpine regions of the Ural mountains have turned attention to the fact that the peaks of mountains rising above the upper fringe of forest growth often form quite flat surfaces while their slopes form steps. In the scientific literature, these forms are called 'altiplanation terraces.' Several hypotheses have been advanced for explaining the origin of such stepped relief of the mountain peaks. Considerable advance in understanding the origin of altiplanation has occurred since a study in detail was begun in order to understand the processes of frost weathering and the displacement of clastic material under the effect of gravitational force, which is now combined under the name goletz denundation.
