The Lena Plateau is located in the southern Sakha Republic, between the Lower Tunguska River in the west and the Amga River in the east. It extends roughly to the north along the left bank of the Lena River for more than 1,000 kilometers (620 mi) with an average width of 200 kilometers (120 mi). The Central Siberian Plateau, is located to the northwest and the Central Yakutian Lowland to the north. To the south, beyond the Aldan, rise the Olyokma-Chara Plateau and the Aldan Highlands.[2]
The average height of the Lena Plateau surface is between 450 meters (1,480 ft) and 500 meters (1,600 ft). Elevations become slightly higher towards the south of the plateau, reaching a maximum height of 700 metres (2,300 ft) at an unnamed summit. The plateau is located in a permafrost zone where the soil freezes down to hundreds of meters.
There are taiga forests made up mostly of pine and larch in the higher areas. Wetlands and meadows are common in the river valleys cutting across the plateau.[6]
The plateau is characterized by a harsh continental climate, with long cold winters and sparse amounts of snow. In winter the temperature may drop to −45 °C (−49 °F), and sometimes even down to −60 °C (−76 °F). Summers are moderately warm with temperatures reaching 15 °C (59 °F) to 17 °C (63 °F). Precipitation is between 350 millimeters (14 in) and 450 millimeters (18 in) per year. Most of the yearly precipitation falls in the summer in the form of rain.
