The ad-Dahna Desert is the central division of the Arabian Desert. It is a corridor of sandy terrain forming a bow-like shape that connects an-Nafud desert in the north to Rub' al-Khali desert in the south. Its length is more than 1000 km siding Twaik Mountains from the east and does not exceed 80 km in width. It is also considered the geographical margin separating Al-Ahsa Province from Najd.
Al-Dahna desert is formed of high sand dunes spreading horizontally which are called veins (ar: عروق), mostly red in color since it contains Iron Oxides.

Famous quotes containing the word desert:
“Full many a gem of purest ray serene,
The dark unfathom’d caves of ocean bear:
Full many a flower is born to blush unseen,
And waste its sweetness on the desert air.”
—Thomas Gray (1716–1771)
