Along the coast of the Lena River vertically elongated rock formations of rare beauty are towering 150 kilometers away from Yakutsk - the Lena Pillars. Their length is 40 kilometers and their height reaches more than 100 meters. These rock formations aged almost half a million years, are a UNESCO World Heritage Site. Tourists perceive the Pillars as the stone fingers or mighty warriors, the legs of fairy dragon or even a miraculous castle.
The origin of this natural monument comes from the deep past. It is believed that in the Cambrian period (540-560 million years ago) in the territory of Yakutia there was a shallow warm sea, the bottom of which accumulated a variety of ancient marine sediments. Gradually, they had turned into strong rocks - those whimsical cliffs, which the Lena Pillars represent now. Even now, amidst the wreckage of rocks one can find imprints of the Cambrian organisms - trilobites.
The geological structure of the Lena Pillars is an outstanding evidence of the history of development of the Earth and its living population. Numerous remains of ancient organisms are unique evidence of the important stages in the history of the organic world. Lena Pillars area is the burial place of the remains of mammoth fauna: mammoth (Mammulhus primigenius Blum.), bison (Bison priscus Boj.), woolly rhinoceros (Coelodonta antiguibatis Blum.), Lena horse (Eguus lenensis Russ.), and reindeer (Rangifer tarandus L.).
Since 1994, the Lena Pillars is a natural park with an area of 485 thousand hectares. As a reserve the Lena Pillars are in the top of eco-tourism in the Republic of Sakha (Yakutia).
