Lena Pillars is a geological formation located on the banks of the Lena River in Khangalassky Ulus, 104 kilometers from the city of Podolsk.

This natural formation is a complex of vertically stretched rocks that extend along the entire bank of a river. Between the villages of Tit-Ary and Petrovskoe Lena Pillars reach the highest density. The height of the rocks reaches 100 meters. It leaves a great impression!

It is known that the formation of rock began 560-540 million years ago, and the relief of the pillars acquired about 400 thousand years ago. The rifts and deep river valleys appeared due to the elevation of the Siberian continental plate, as a result, there was an activation of karst processes that gave rise to such original rock forms.
