Ulaxan Aan
Ulakhan-An lies on the left bank of the Lena near the mouth of the Ulakhan-An-Yuryakh. Its Sakha name means the great gateway. The river valley carried a long route from the southern interior to Yakutsk, and in the eighteenth century Ulakhan-An was among the postal stations established along it. Horses and drivers at these stations carried travellers and messages onward through the vast country beside the Lena.
