Lena Pillars is the name given to a natural rock formation along the banks of the Lena River in far eastern Siberia. The pillars are 150–300 metres high, and were formed in some of the Cambrian period sea-basins. The highest density of pillars is reached between the villages of Petrovskoye and Tit-Ary.

Yakutia (Russian: Яку́тия, yah-KOO-tee-yuh), also known as the Republic of Sakha, is located in the Russian Far East, and is notable for being the world’s largest subnational governing body by area. Yakutia covers an area of more than 3 million km², representing about 18 percent of the Russian Federation, and making it roughly the size of India, despite having a population smaller than that of Rhode Island. The republic’s capital is Yakutsk.

Yakutia borders Chukotka to the northeast, Magadan Oblast and Khabarovsk Krai to the southeast, Amur Oblast to the south, Zabaykalsky Krai and Irkutsk Oblast to the southwest, Evenkia to the west and Taymyria to the northwest. In the north it has a long coastline with the Arctic Ocean.
