To the north of Chemngal were the Oropom (Orupoi), a late neolithic society whose expansive territory is said to have stretched across Turkana and the surrounding region as well as into Uganda and Sudan. Wilson (1970) who collected traditions relating to the Oropom observed that the corpus of oral literature suggested that, at its tail end, the society "had become effete, after enjoying for a long period the fruits of a highly developed culture". Bordering the Maliri in Uganda were the Karamojong, an iron age community that practiced a pastoral way of life.
