reg
REG
A flat, stony desert surface — a plain of gravel and pebbles from which the finer sand and dust have been removed by wind, leaving behind a lag deposit of coarse material. Reg is the most common desert surface type worldwide, though it is less famous than the erg. It is the desert stripped to its bones — nothing soft, nothing loose, nothing growing. Walking on reg is walking on an infinite gravel parking lot.
Etymology
Arabic, meaning a stony desert plain. Like erg, the word entered English through French North African usage.
Notes
Reg is closely related to desert pavement but describes the terrain at a larger scale — desert pavement is the surface; reg is the landscape.
