Lena River Delta – is rather a rare case of a huge alluvial deltaic cone formation (the area is up to 28,500 km2). The top of the estuary is a head of the forest left arm – Burlukskaya Protoka. 70 km down the river close to the cliffy cape Krest-Tumsa and Stolb Island, there is a main point of the Lena’s division into large arms (protokas) – Olenyokskaya, Tumatskaya, Trofimovskaya, and Bykovskaya.
