The Dahl is Located at a distance of about 100 kilometers
southwest of Rafha (on the northern border of Saudi Arabia), and
approximately 13 kilometers south of the ancient village of
Luqah, which local people and travellers used to visit in search
of water. Luqah was also a center of trade between people in
this area and traders from the north. Here can be found many old
wells, some dating to the Abbasid caliphate and some all the way
back to the prophet Solomon.
General Description of the Dahl:
From the surface, Dahl Luqah appears to have the form of a
vertical slot with a small diameter of 120 centimeters. From
this slot, visitors must climb down a metal ladder through a
vertical pipe to a depth of 4 meters and then crawl horizontally
through the tunnel-floor mud, where they will encounter large
quantities of fallen rocks, some bags of trash, and dead sheep.
Beetles abound in large numbers in this area. The length of this
tunnel is 6 meters with a width of 90 centimeters and a height
After crawling through the narrow tunnel, the ceiling starts to
rise to about 1.5 meters, with mud visible on the southern side
floor of the tunnel of this dahl, as well as a great many rocks
which have fallen on the floor.
If you continue along the tunnel for about 46 meters, you will
see the effects of the water surging through it, causing erosion
and leaving large quantities of limestone rocks scattered on the
floor, as well as causing the disappearance of formations
(stalactites) on the roof of this Dahl. Here, a small number of
stalagmites may be seen in some places.
Description of Dahl Luqah from a geological perspective:
Dahl Luqah was formed in the limestone rocks of the Formation Um
Erudumah (55 million years old), as a result of the ancient
climate affecting these rocks through slightly acidic rainwater
and flooding. In time, this water followed cracks deep beneath
the surface and dissolved the limestone.
As a result of this process, Dahls appeared in the Um Arudumah
formation both in the limestone beds and in layers of gypsum.
Erosion, chemical weathering and water flow continued to develop
the dahl into what we see today. These forces caused rocks to
fall from the ceiling in great quantities and eventually reduced
them to a fragile, chalky consistency.
Live animals inside the Cave
A large number of wild pigeon eggs were seen on the floor next
to the cave’s vertical entrance. Wild pigeons and their nests
were found in total darkness, as far as 35 meters inside the
cave. In addition, there were hundreds of Beetles crawling on
the floor, just as we were.
