The Indian Himalayan Region (IHR) is a range that spans ten states of India namely, Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, and Arunachal Pradesh as well as the hill regions of two states - Assam and West Bengal.〔( The Himalaya (abode of snow) )〕 The region is responsible for providing water to a large part of the Indian subcontinent and contains varied flora and fauna.〔(Sustainable development of the Indian Himalayan region : Linking ecological and economic concerns )〕 The IHR physiographically, starting from the foothills of south (Siwaliks), this mountain range extends up to Tibetan plateau on the north (Trans-Himalaya). Three major geographical entities, the Himadri (greater Himalaya), Himanchal (lesser Himalaya) and the Siwaliks (outer Himalaya) extending almost uninterrupted throughout its length, are separated by major geological fault lines. Mighty but older streams like the Indus, Sutlej, Kali, Kosi and Brahmaputra have cut through steep gorges to escape into the Great Plains and have established their antecedence. The Northern-most range of mountains are the Karakoram Mountains that continue into Pakistan and China. India claims most of the Chinese and Pakistani Karakoram as its territory and this has been one of the defining features of the Kashmir Conflict To the south of the Karakoram range lie the Zangskar ranges. Parallel to the Zangskar ranges lie the Pir Panjal ranges. These three mountain ranges lie parallel to each other in the north-western part of India, most of its area lying in the state of Jammu and Kashmir. Some of the highest mountains on earth are found in the region. Many rivers considered holy like the Ganga and Yamuna flow from the Himalayas. ==Trans-Himalayas== Trans himalay is created due to the collision with eurasian plate.This Zone is the Northern most area in the country in the states of Jammu and Kashmir and Himachal Pradesh. It is an extension of Tibetan plateau around the Himalayas. The Main Himalayan Ranges are: *Pir Panjal Range *Dhaula Dhar Range *Zanskar Range *Ladakh Range *East Korakoram Range 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Indian Himalayan Region」の詳細全文を読む スポンサード リンク
