Ymyakhtakh culture is a culture of Siberia…
2637 BCE to 909 BCE
Its origins seem to be in the Lena river basin of Yakutia, and also along the Yenisei river; individual sites will also be found in Taymyr.
The culture is named after Ymyyakhtakh, a settlement in the Sakha Republic, Russia.
From there it spreads both to the east and to the west.
