The Lena Pillars are a geological formation and a natural park of the same name in Russia, on the banks of the Lena River. It is located in the Khangalassky ulus of Yakutia, 104 km from the city of Pokrovsk. The Lena Pillars are a complex of vertically elongated rocks stretching for many kilometers, bizarrely piling up along the shore of the Lena, a deep valley cutting through the Prilensky plateau. The greatest density of the pillar is reached between the villages of Petrovsky and Tit-Ara.Solid areas: 1%
