Dunes of Dakhara
The Oued Righ is a long oasis depression in the northern Sahara, with Touggourt among its chief settlements. Date-palm groves draw on underground water, while dunes and dry ground surround the cultivated land. The oases of Ouargla continue the chain farther south. In the late eighteenth century the rulers of Touggourt competed with those of nearby Tamacine, another oasis and market centre in this desert region.
