[2] The first reference to Khomarlu in the published literature, is the following description by Robert Mignan, "..the village of Khomorloo, situated upon a deep ravine, between steep calcareous and barren mountains.

The dwellings of the villagers were scooped from the sides of a mountain, which formed three sides of each hut, the fourth being a wall of mud, in which an aperture of four feet square was left, and a few miserable planks tied together served for the door: the whole covered over by rafters, and a thin coating of flat thatch.

In the wake of White Revolution (early 1960s) a clan of Mohammad Khanlu tribe, comprising 60 households, used Khomarlu as their winter quarters.
