the northen mountains
the great himalayas:The Great Himalayas lie north of the Lower Himalayan Range. These mountains are bounded by the Indus River in the north and the west as the river takes a southward turn at Sazin. The average height of the range is about 6000 meters. Some of the highest peaks in the world lie in these mountains e.g. Nanga Parbat (8126 meters), which is the ninth highest peak in the world and the second highest peak in Pakistan. Since the mountains are perpetually covered with snow there are many glaciers, with Rupal Glacier being the longest (17.6 km). The glacial action has created many beautiful lakes like the Saiful Muluk lake which lies in the upper Kaghan Valley. Another noticeable geographic feature of this area are the deep gorges carved by the Indus in this region. The deepest of which, located at Dasu-Patan region (Kohistan District), is 6500 meters deep. In fact, this is the deepest gorge in the world, so deep, that even if the highest mountain of North America, Europe or Antarctica were to be placed at its deepest point, the peak would still not project beyond the top. the lesser himalayas:
The Lesser Himalayas lies in between the Sub-Himalayas and Higher Himalayas separated by the Main Boundary Thrust (MBT) and the Main Central Thrust (MCT) respectively. The total width ranges from 60–80 km. The Lesser Himalayas is made up mostly of the unfossiliferous sedimentary and met sedimentary rocks; such as shale, sandstone, conglomerate, slate, phyllite, schist, quartzite, limestone and dolomite. The rocks range in age from Precambrian to Miocene. The geology is complicated due to folding, faulting and thrusting and are largely unfossiliferous. Tectonically, the entire Lesser Himalayas consists of two sequences of rocks: allochthonous, and autochthonous-Para autochthonous units; with various nappes, klippes and tectonic windows. the outter himalayas:
The Outer Himalayas : The altitude of this zone ranges from 350 meters (1050...
