This serial property consists of two desert sites, including Jabal Umm Sinman in Jubbah and the Al-Manjoor and Rata mountains in Al-Shuwaymis. As for the Umm Senman Heights range, it overlooks a freshwater lake of which no trace remains at the present time. It used to provide water for people and animals in the southern part of the Great Nafud Desert. The ancestors of the current Arab population groups left traces indicating their presence. This is found in many rock inscription panels and many other inscriptions. The Almanjoor and Rata Mountains form rocky slopes of a valley that is currently covered with sand and represents a large number of human and animal forms dating back 10,000 years.
