Shadah Al-asfal Mountain is characterized by the abundance of large granite rocks, especially those standing rock masses called Nadba, which are almost two hundred meters long. The mountain also has several dark plateaus and caves under the rocks. Dr. Ahmed Qashash, a researcher in archaeology, said: "Shadah Al-asfal Mountain and Shadah Al-a'laa Mountain, are composed of
granite igneous rocks that have been uplifted and exposed since ancient times as a result of mountain-building earth movements, dating back to the
Precambrian periods which is the earliest geologic age in the history of the earth's formation. The natural features of these two mountains include caves and caverns, formed by millions of years of erosion, others were formed by the infiltration of gases from the
magma during
crystallization into the outer part of the magma, leaving spherical, rectangular, or elliptical cavities in their place, they vary in size from rock to rock and are very abundant in these two mountains, especially the Shadah Al-asfal Mountain. Other caves are formed when huge boulders fall on top of other rocks, creating large cavernous spaces between them. These caves are fortified natural habitats that have been inhabited by humans since the first man, and remain an ideal home for the people of these two mountains." == Villages ==
