Jhelum District, is partially in Pothohar Plateau of the Punjab province of Pakistan. The district of Jhelum, which covers an area of 3,587 square kilometres (1,385 sq mi),[6] Jhelum City is the main city of the district. The district of Jhelum stretches from the river Jhelum almost to the Indus. Salt is quarried at the Mayo mine in the Salt Range. There are two coal mines in the district from which the North-Western railway obtains parts of its supply. These are the only coal mines in Punjab province which are in working condition. The chief center of the salt trade is Pind Dadan Khan. The district is crossed by the main line of the North-Western railway and also traversed along the south by a branch line. It is located in the north of the Punjab province, Jhelum district is bordered by Sargodha and Mandi Bahauddin to its south, Khushab to its southwest, Jhelum River to its south and east, Gujrat to its east, Chakwal to its west, Mirpur to its northeast, and Rawalpindi to its north. The district capital, Jhelum City, is situated on the right and left bank of the Jhelum River, the left side of Jhelum is known as Sarai Alamgir and it also contains the Military College Jhelum (MCJ). The river Jhelum is navigable throughout the district, which forms the south-eastern portion of a rugged Himalayan spur, extending between the Indus and Jhelum to the borders of the Sind Sagar Doab. Its scenery is very picturesque and is lighted up in places by smiling patches of the cultivated valley. The backbone of the district is formed by the Salt Range, a treble line of parallel hills running in three long forks from east to west throughout its whole breadth. The range rises in precipices, broken by gorges, clothed with brushwood, and traversed by streams which are at first clear but become impregnated with the saline matter over which they pass. Between the line of hills lies a table-land, in which the small lake of Kallar Kahar nestles amongst the minor ridges. North of the Salt Range, the country extends upwards in an elevated plateau, diversified by a number of ravines and fissures, until it loses itself in tangled masses of Rawalpindi mountains. In this rugged tract, cultivation is rare and difficult, the soil being choked with saline matter. At the foot of the Salt Range, however, a small strip of level soil lies along the banks of the Jhelum and is dotted with prosperous villages.
