In southwestern Punjab, the mountains extend into the two districts of Dera Ghazi Khan and Rajanpur, which are located west of the Indus River on the boundary with Balochistan. Bordering the mountains to the east are the plains of the Indus River valley, and to the north are the arid highlands of the Central Hindu Kush whose heights extend up to 3,383 metres (11,099 ft). The total area on which this range spans around 6475 sq. km .Together with the Kirthar Mountains on the border between Balochistan and Sindh, the Sulaiman Mountains form what is known as the Sulaiman-Kirthar geologic province.
