The 80 km long Lena Pillars (Lenskie Stolby), a 35-million-years-old strech of Kimberly limestone, about 200 km south of Yakutsk in East Siberia, are of utmost beauty. So is the Lena river going all the way, over four thousands kilometers, to the Laptev Sea at the Arctic.

Yet of quite different geological formation, actually volcanic rock pillars, but as much beautiful are the "Yenisey stolby", near Krasnoyarsk, in West Siberia, on the banks of the great Yenisey river, going also thousands of kilometers to the Arctic and emptying at the Kara Sea.
