Boruulaax

Boruulaax is a left-bank tributary of the Amga in the forested country between the Lena and Aldan. Its waters join the Amga on the long journey north to the Aldan and eventually the Lena. The surrounding plateau is cut by streams and wooded valleys; in this continental climate, the rivers spend much of the year under ice and swell as the snow melts in spring.
