The geological structure of the Lena Pillars captures outstanding evidence of the history of the development of the Earth and its living population. The numerous remains of ancient organisms found here represent the preserved unique evidence of the most important stage in the history of the organic world and the "explosion" of biological diversity that took place in the Lower Cambrian.
Also in the area of Lena Pillars, burials of the remains of representatives of the mammoth fauna were found: mammoth (Mammulhus primigenius Blum), bison (Bison priscus Boj), woolly rhinoceros (Coelodonta antiguibatis Blum), Lena horse (Eguus lenensis Russ), reindeer (Rangifer)
Various permafrost landforms are widely represented on the territory of the park (permafrost karst, baidzharakhs, bulgunyakhs, swelling mounds, polygonal-wedge ice). On the right bank of the Lena River, there are small areas of waving tukulan sands - a unique landscape with elements of a cold northern sandy desert.
Within the boundaries of the park, 464 species, 276 genera and 81 families of vascular plants have been identified. A narrow-area endemic, Redowskia sophiifolia, is found only here and nowhere else in the world. In addition, 12 more species from the Red Data Book are found in the area of the Lena Pillars.
The territory is characterized by a peculiar combination of faunal complexes. Here, along with the dominant forest elements, there are also representatives of the mountain-taiga (musk deer, red deer) and mountain-steppe (northern pika) complexes. The park is home to 42 species of mammals. The fauna of nesting birds is represented by 99 species, 27 of which are listed in the Red Data Books of various levels. The small swan, peregrine falcon, gyrfalcon, white-tailed eagle, golden eagle, osprey, Siberian Siberian Crane are included in the Appendices to the CITES Convention and are protected species of the world's avifauna.
Lena Pillars are distinguished by their exceptional beauty and, in terms of their aesthetic impact on humans, are unmatched in the vast territory of North-East Eurasia. Fabulous stone sculptures in the form of bizarre pillars, spiers, towers with niches, passages, caves stretch along the river banks for tens of kilometers.
