Crossing Rohtang Pass !!!

Rohtang Pass (Hindi: रोहतांग दर्रा) (Bhoti: Rohtang , lit: pile of corpses,due to people dying in bad weather trying to cross the pass) (altitude 3,978 m or 13,051 ft), is a high mountain pass on the eastern Pir Panjal Range of the Himalayas around 51 km (32 mi) from Manali. It connects the Kullu Valley with the Lahaul and Spiti Valleys of Himachal Pradesh, India.

The pass provides a natural divide between the sub-humid/humid Kullu Valley with a primarily Hindu culture (in the south), and the arid/semi-arid high-altitude Lahaul and Spiti valleys with a Buddhist culture (in the north). The pass lies on the watershed between the Chenab and Beas basins. On the southern side of this pass, the Beas River emerges from underground and flows southward[3] and on its northern side, the Chandra River, a source stream of the river Chenab, flows westward.
