Sixty million years ago, a thick layer of limestone was slowly formed at the bottom
of a shallow sea. Today, that same rock formation lies beneath the vast deserts of
Saudi Arabia. Alongside the Dahna sand dunes, not far from Riyadh, the Umm-Er-
Radhuma limestone is riddled with countless holes known locally as Dahls. Since the
1980's a number of beautiful and sometimes curious caves have been found in this
area and reports on them have appeared in various publications
Qasr Zabal at Sakakah.
