Mountains Of India


The great Himalayas, the highest mountain range in the world, extend along the northern frontiers of Pakistan, India, Nepal, Bhutan, and Burma. They were formed geologically as a result of the collision of the Indian subcontinent with Asia.

This process of plate tectonics is ongoing, and the gradual northward drift of the Indian subcontinent still causes earthquakes (see Earthquakes, this ch.). Lesser ranges jut southward from the main body of the Himalayas at both the eastern and western ends.

The Himalayan system, about 2,400 kilometers in length and varying in width from 240 to 330 kilometers, is made up of three parallel ranges--the Greater Himalayas, the Lesser Himalayas, and the Outer Himalayas--sometimes collectively called the Great Himalayan Range.


The Greater Himalayas, or northern range, average approximately 6,000 meters in height and contain the three highest mountains on earth: Mount Everest (8,796 meters) on the China-Nepal border; K2 (8,611 meters, also known as Mount Godwin-Austen, and in China as Qogir Feng) in an area claimed by India, Pakistan, and China; and Kanchenjunga (8,598 meters) on the India-Nepal border. Many major mountains are located entirely within India, such as Nanda Devi (7,817 meters) in the state of Uttar Pradesh.

The snow line averages 4,500 to 6,000 meters on the southern side of the Greater Himalayas and 5,500 to 6,000 on the northern side.

Because of climatic conditions, the snow line in the eastern Himalayas averages 4,300 meters, while in the western Himalayas it averages 5,800 meters.


The Lesser Himalayas, located in northwestern India in the states of Himachal Pradesh and Uttar Pradesh, in north-central India in the state of Sikkim, and in northeastern India in the state of Arunachal Pradesh, range from 1,500 to 5,000 meters in height. Located in the Lesser Himalayas are the hill stations of Shimla (Simla) and Darjiling (Darjeeling). During the colonial period, these and other hill stations were used by the British as summer retreats to escape the intense heat of the plains. It is in this transitional vegetation zone that the contrasts between the bare southern slopes and the forested northern slopes become most noticeable.

The Outer or Southern Himalayas, averaging 900 to 1,200 meters in elevation, lie between the Lesser Himalayas and the Indo-Gangetic Plain. In Himachal Pradesh and Uttar Pradesh, this southernmost range is often referred to as the Siwalik Hills. It is possible to identify a fourth, and northernmost range, known as the Trans-Himalaya.




This range is located entirely on the Qinghai-Xizang Plateau, north of the great west-to-east trending valley of the Yarlung Zangbo River. Although the Trans-Himalaya Range is divided from the Great Himalayan Range for most of its length, it merges with the Great Himalayan Range in the western section--the Karakoram Range--where India, Pakistan, and China meet.The southern slopes of each of the Himalayan ranges are too steep to accumulate snow or support much tree life; the northern slopes generally are forested below the snow line. Between the ranges are extensive high plateaus, deep gorges, and fertile valleys, such as the vales of Kashmir and Kulu. The Himalayas serve a very important purpose.

They provide a physical screen within which the monsoon system operates and are the source of the great river systems that water the alluvial plains below (see Climate, this ch.). As a result of erosion, the rivers coming from the mountains carry vast quantities of silt that enrich the plains.



The area of northeastern India adjacent to Burma and Bangladesh consists of numerous hill tracts, averaging between 1,000 and 2,000 meters in elevation, that are not associated with the eastern part of the Himalayas in Arunachal Pradesh. The Naga Hills, rising to heights of more than 3,000 meters, form the watershed between India and Burma. The Mizo Hills are the southern part of the northeastern ranges in India. The Garo, Khasi, and Jaintia hills are centered in the state of Meghalaya and, isolated from the northeastern ranges, divide the Assam Valley from Bangladesh to the south and west.

Worlds Beautiful Mountains

Information Including Topography

The Andes Mountains stretch over 5500 miles from the southern tip of Argentina and Chile to the northern part of Columbia in South America. With many peaks and active volcanoes over 20,000 feet, including the highest peak Cerro Aconcagua (elevation 22,826, located on the Chile and Argentina border). This majestic region is second only to the Himalayas in size and average elevation. With the high snow covered mountains as a spectacular backdrop, fishing for trout and Atlantic salmon can be an unforgettable experience.


Los Glaciares National Park


This magnificent park is located in the Southern part of the Andes on Chile and Argentina border.  The Patagonian Ice Field extends to over half the park and comprises of over two hundred glaciers and is considered to be the largest ice field outside of Antarctica.  The view of the glaciers and hearing the thundering sounds of the ice falling create an awesome experience of nature at its best.


The area is also populated by prehistoric and ancient Indian sites consisting of  hunter-gatherers and the Tehuelches Indians, who were almost dissipated by the European colonization of the region.

Fly Fishing

The numerous ice fields and glaciers, not only give hikers a great trekking experience, but the waters flowing from the Patagonian Ice Field produce abundant water for fly fishing. The many lakes and rivers, climate, as well as foliage in and around this rugged region produce abundant insect life for large rainbow, brook and brown trout. The trout that was introduced to the Chile and Argentina region in the early 20th century from Europe and North America adapted to the cold and clear waters that flowed from the mountains and created fishing paradise for the fly fishing enthusiasts.

TRANSYLVANIAN MOUNTAINS

TRANSYLVANIAN MOUNTAINS, the general name of the mountain system which surrounds the Transylvanian highland or plateau on all four sides, and forms the south-eastern and southern continuation of the Carpathian system (q.v.). At the mouths of the Viso and the Golden Bistritza, where the Eastern or Wooded Carpathians end, the range of mountains divides and sends ramifications in two directions, to the south and to the west. These chains which enclose Transylvania, giving it the general aspect of a great natural fortress, are the most eastern offshoots of the mountain system of central Europe, and guard the approach from the east to the great Hungarian plain. They slope gently towards the interior of Transylvania, but rather abruptly towards Rumania and while the western wall possesses several large and easy passes, the eastern and southern walls are much more difficult to cross.

The eastern wall of the Transylvania quadrilateral is composed of two parallel anges of mountains divided by the valleys of the Maros and Aluta. The outer range is composed of the following groups: the Gyergy6 Mountains (including the Kelemen range) with the highest peaks Kelemenhavas (6600 ft.) and Pietrosul (6908 ft); the Csik Mountains with the highest peaks Nagy-Hagymas (59 00 ft.) and the volcanic Biidels (3300 ft.); and the Bereczk Mountains with the highest peak Lakocza (5830 ft.). The inner range is composed of the following groups: the Giirgeny Mountains with the highest peak Mezohavas (5826 ft.); the Hargitta Mountains with the highest peak Hargitta (5900 ft.); and the Barota Mountains with the highest peak Kukukhegy (5120 ft.). Near the mouths of the Maros and the Aluta are situated the celebrated GyorgyO valley, one of the most beautiful in the whole Transylvania, and the famous Borszek valley with its mineral springs.



The southern wall of the Transylvanian highland is occupied by the Transylvanian Alps. They have a length of 230 m., and are the highest and wildest mountain range of the whole Transylvanian system, resembling the High Tatra in their bold and high peaks, their beautiful scenery, and their flora. The Transylvanian Alps rise to an altitude of 7200 ft. above the level of the Danubian (Rumanian) plain, and are divided into a considerable number of groups. From east to west these groups are: the Bodza Mountains with the highest peak Csukas (Ciucas, 6424 ft.); the Burzenland Mountains with the beautiful peaks of Bucsecs (8230 ft.), Kiinigstein (7352 ft.) and Schuler (5910 ft.); the high Forgaras group, extending to the Roteturm pass, and containing Negoi (8345 ft.), the highest peak in the Transylvanian mountains, Butyan (8230 ft.) and Surul (7482 ft.). West of the Roteturm pass the Transylvanian Alps are also known under the name of the Hatszeg Mountains, and consist of the following groups: the Cibin Mountains with the highest peak Cindrel (7366 ft.); the Paringul Mountains with the highest peak Mandra (8260 ft.); the Vulkan Mountains, and the Hatszeg Mountains proper with the beautiful peak Retiezat (8125 ft.). The south-western part of the Transylvanian Alps is formed by the Cserna or Ruszka Mountains with the highest peak Verfu Petri (8140 ft.) whose offshoots, of a mean altitude of 3200-4700, known as the Banat Mountains, fill the Banat. The southern part of the Cserna Mountains, known as the Stretinye Mountains, extend to the Danube, and together with the Miroch Mountains, on the right side of the Danube, and belonging, therefore, to the Balkan system, form the famous gorge of the Iron Gate near Orsova.

The western and northern wall of the Transylvanian quadrilateral do not present the character of an uninterrupted chain of mountains, but possess many low and easy passes towards the Hungarian plain. Going from south to north the principal groups are: the Transylvanian Ore Mountains with the basaltic mass of the Detunata (3768 ft.) near Abrudbanya; the Bihar Mountains, with romantic scenery and numerous caverns, with the highest peak the Cucurbeta (6045 ft.); to the east of this group are the Aranyos Mountains with the highest peak, the Muntelui Mare (5970 ft.), to the south-west of Kolozsvar; then come the Meszes group and the Kraszna Mountains. The northern wall is formed by the Lapos Mountains with the highest peak Ciblesiu (6020 ft.), and the Rodna Mountains with the highest peaks Muncsel (5835 ft.), Pietrosu (7544 ft.) and Ineu (74 8 4 ft.).



Inside this mountainous quadrilateral lies the Transylvanian highland or plateau, which has a mean elevation of1000-1600ft. It is improperly called a plateau, for it does not possess anywhere extensive pla;ns, but is formed of a network of valleys of various sizes, ravines and canons, united together by numerous small mountain ranges, which usually attain a height of 500-800 ft. above the altitude of the valley.

In the Transylvanian Mountains the principal passes are: the Rodna, the Borgo, the Tdlgyes and the Baas. Then come the Gyimes, the Uz and Oitoz, the Bodza or Buzeu, the Tomos or Predeal pass, crossed by the railway from Brasso to Bucharest, the famous Roteturm pass (1115 ft.) through the narrow gorge of the Aluta, crossed by the railway from Nagy-Szeben to Bucharest, the Vulkan, the Teregova pass, and the Iron Gate pass, both crossed by the railway from Temesvar to Craiova. All those passes lead from Transylvania into Rumania. From Transylvania into Hungary are the Banffy-Hunyad pass, crossed by the railway from NagyVarad to Kolozsvar, and the. defile of the Maros crossed by the railway from Arad to Broos. In the interior of Transylvania are the Szent-Domokos pass near Csik-Szereda leading from the valley of the Aluta to that of the Maros (near their respective mouths), and the pass of Csik-Szereda over the Hargitta Mountains.
