Geography and Geology
The height is skew in a meridional direction: its northern slope very abruptly goes down to Volga and southern has a very weak bias, forming a wide plateau cut up by a labyrinth of ravines. In the western part of Zhiguli is separated from a plateau by the valley of the Otvazhinskiy Ravine, extended in a latitudinal direction. In the central, highest part Zhiguli absolutely imperceptibly pass in a plateau, and its maximum point was found only by means of tools as externally it is not allocated on almost flat surface in any way.
At tops, rocks and other rocky exposures of Zhiguli there are the most ancient geological breeds on a surface which have generated 230-350 million years ago in the Permian and Carboniferous periods. Sediment of these systems is presented mainly by limestones and dolomite. The slopes of Zhiguli are mostly formed by products of aeration of the Permian and Carboniferous breeds.

Famous quotes containing the words geography and and/or geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
