In the Ust-Chirkuo Site (Yakut: Чиркуо төрдө, romanized: Çirkuo tördö) there are remains of ancient settlements by the river.[2] Currently there are no permanent inhabited places in the river area.[3]

Course
The Chirkuo lies in the upper stretch of the Vilyuy basin. It begins at the confluence of the Duikhta and the Kucchuchi-Chuurka (Куччучи-Чуурка) in the Vilyuy Plateau. The river flows roughly northwards across the plateau along the border with Irkutsk Oblast to the west. Finally it meets the right bank of the Vilyuy 1,712 km (1,064 mi) from its mouth in the Lena. The river freezes between mid October and late May.[4]
The main tributaries of the Chirkuo are the 120 kilometres (75 mi) long Golusakh and the 88 kilometres (55 mi) long Dulisma from the left. The last stretch and mouth area of the Chirkuo are part of the backwater of the Vilyuy Reservoir.[5]
