 In the nineteenth century some writers identified the valley with the wadi al-Qelt, a deep ravine located to Jericho's south.In the twentieth century the Hyrcania valley (El-Buqei'a in Arabic) west and south of Qumran, and Wadi en-Nu'eima have also been suggested.One difficulty is that the narrative of Joshua  appears to place the valley of Achor to the north of Jericho, between Jericho and Ai; but Joshua makes the valley part of the boundary between the tribe of Judah and the tribe of Benjamin, to the south of Jericho, but not as far south as El-Buqei'a.
