Hamada
From Wikipedia, the free encyclopedia
For other uses, see Hamada (disambiguation).
A hamada (Arabic, حمادة ḥammāda) is a type of desert landscape consisting of largely barren, hard, rocky plateaus, with very little sand.[1] A hamada may sometimes also be called a reg (pronounced "rej"), though this more properly refers to a stony plain rather than a highland.[2]
Hamadas exist in contrast to ergs, which are large areas of shifting sand dunes.[3][4]
The world's largest hamada is the Hamada du Draa,[citation needed] in the northwest Sahara desert, between Morocco, Algeria and Western Sahara. Hamada areas form 70% of the Sahara desert.[citation needed]
