The Lower Himalayan Range also called the Lesser Himalayas or Himachal is one of the four parallel sub-ranges of the Himalayas. [1] [2] It has the Great Himalayas to the north and the Sivalik Hills to the south. It extends from the Indus River in Pakistan to the Brahmaputra Valley in North East India traversing across North India, Nepal and Bhutan. [3] The sub-range has an average elevation of 3,700–4,500 m (12,100–14,800 ft). [4]
Southern slopes of the Himachal Range are steep and nearly uninhabited due to a major fault system called the 'Main Boundary Thrust". The crest and northern slopes slope gently enough to support upland pastures and terraced fields. Nepal's densely populated Middle Hills begin along the crest, extending north through lower valleys and other "hills" until population thins out above 2,000 m and cereal-based agriculture increasingly gives way to seasonal herding and cold-tolerant crops such as potatoes.
Most ethnic groups found along the Himachal Range and northward into the Middle Hills have Tibeto-Burman affinities including Nepalese origins of Newar, Magar, Gurung, Tamang, Rai and Limbu, however the most populous ethnic group is Indo-European Hindus called Paharis, mainly of the upper Brahman, and Kshatriya, or Chhetri castes. Lower terrain south of the escarpment was historically malarial and inhabited by apparently aboriginal peoples with evolved immunity, notably the Tharu and Maithili people.
The Himachal Range is an important hydrographic barrier crossed by relatively few rivers. Drainage systems have evolved candelabra configurations with numerous tributaries flowing south from the Himalaya through the Middle Hills, gathering immediately north of the Himachal Range and cutting through in major gorges as the Karnali in the west, the Gandaki or Narayani in central Nepal, and the Kosi in the east. With temperatures persisting around forty degrees Celsius in the plains of India from April until the onset of the summer monsoon in June, but ten to fifteen degrees cooler atop the Himachal Range, various Hill Stations have developed in the region.

The remainder of Dang and part of Salyan district are drained by the Babai. The remainder of Salyan and all of Rukum districts are drained by the Bheri.
The Indo-Gangetic Plain, also known as the Northern Plain or North Indian River Plain, is a fertile plain spanning 700,000 km2 (270,000 sq mi) across the northern and north-eastern part of the Indian subcontinent. It encompasses northern and eastern India, eastern Pakistan, southern Nepal, and almost all of Bangladesh. It is named after the two major river systems that drain the region–Indus and Ganges.
The Sivalik Hills, also known as Churia Hills, are a mountain range of the outer Himalayas. The literal translation of "Sivalik" is 'tresses of Shiva'. The hills are known for their numerous fossils, and is also home to the Soanian Middle Paleolithic archaeological culture.
Dhauladhar is a mountain range which is part of a lesser Himalayan chain of mountains. It rises from the Shivalik hills, to the north of Kangra and Mandi. Dharamsala, the headquarters of Kangra district and the winter capital of Himachal Pradesh, lies on its southern spur in the Kangra Valley. Chamba lies to the North of this range.
The Ganges Basin is a major part of the Ganges-Brahmaputra-Meghna (GBM) basin draining 1,999,000 square kilometres in Tibet, Nepal, India and Bangladesh. To the north, the Himalaya or lower parallel ranges beyond form the Ganges-Brahmaputra divide. On the west the Ganges Basin borders the Indus basin and then the Aravalli ridge. Southern limits are the Vindhyas and Chota Nagpur Plateau. On the east the Ganges merges with the Brahmaputra through a complex system of common distributaries into the Bay of Bengal. Its catchment lies in the states of Uttar Pradesh (294,364 km2), Madhya Pradesh (198,962 km2), Bihar (143,961 km2), Rajasthan (112,490 km2), West Bengal (71,485 km2), Haryana (34,341 km2), Himachal Pradesh (4,317 km2), Delhi, Arunachal Pradesh (1,484 km2), the whole of Bangladesh, Nepal and Bhutan. Several tributaries rise inside Tibet before flowing south through Nepal. The basin has a population of more than 500 million, making it the most populated river basin in the world.
Dang District is a district of Lumbini Province located in the Inner Terai of midwestern Nepal. Deukhuri Valley of the district is the capital of the province and is the second largest valley of Asia surrounded by Sivalik Hills and the Mahabharata Range. The district headquarter Ghorahi is the seventh largest city and the largest sub-metropolitan city of Nepal. Tulsipur sub-metropolitan city, the second largest city of Dang, is a major transportation hub with extensive road and air networks. The district covers an area of 2,955 km2 and has a population of 674,993.
The Pir Panjal Range is a range of mountains in the Lower Himalayan region located in the Western Himalayas of northern Indian subcontinent. It runs southeast to northwest between the Beas and Neelam/Kishanganga rivers, in the Indian state of Himachal Pradesh and Indian-administered union territory of Jammu and Kashmir, with its northwestern end extending into territory administered by Pakistan. The Himalayas show a gradual elevation towards the Dhauladhar and Pir Panjal ranges. Pir Panjal is the largest and westernmost range of the Lesser Himalayas. Near the bank of the Sutlej River, it dissociates itself from the main Himalayan range and forms a divide between the Beas and Ravi rivers on one side and the Chenab on the other. Further west, the Pir Panjal range forms the southwestern boundary of the Kashmir Valley, separating it from the hills of Jammu region, forming a divide between the Jhelum and Chenab rivers.
The Tons is the largest tributary of the Yamuna. It flows through Garhwal region in Uttarakhand, touching Himachal Pradesh. The Tons thrust is named after this river.

The geology of Nepal is dominated by the Himalaya, the highest, youngest and a very highly active mountain range. Himalaya is a type locality for the study of on-going continent-continent collision tectonics. The Himalayan arc extends about 2,400 km (1,500 mi) from Nanga Parbat by the Indus River in northern Pakistan eastward to Namche Barwa by the gorge of the Tsangpo-Brahmaputra in eastern Tibet. About 800 km (500 mi) of this extent is in Nepal; the remainder includes Bhutan and parts of Pakistan, India, and China.
The Himalayan subtropical broadleaf forests is an ecoregion that extends from the middle hills of central Nepal through Darjeeling into Bhutan and also into the Indian States of Uttar Pradesh and Bihar. It represents the east–west-directed band of subtropical broadleaf forest at an altitude of between 500 and 1,000 m along the Outer Himalayan Range, and includes several forest types traversing an east to west moisture gradient.
The Doon Valley is an unusually wide, long valley within the Sivalik Hills and the Lesser Himalayas, in the Indian states of Uttarakhand, Himachal Pradesh and Haryana. Within the valley lies the city of Dehradun, the winter capital of Uttarakhand state.
The Eastern Himalayas extend from eastern Nepal across Northeast India, Bhutan, the Tibet Autonomous Region to Yunnan in China and northern Myanmar. The climate of this region is influenced by the monsoon of South Asia from June to September. It is a biodiversity hotspot, with notable biocultural diversity.
The Soanian culture is a prehistoric technological culture from the Siwalik Hills, Pakistan. It is named after the Soan Valley in Pakistan.
The Indian Himalayan Region is the section of the Himalayas within the Republic of India, spanning thirteen Indian states and union territories, namely Ladakh, Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, West Bengal, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Assam, and Arunachal Pradesh. The region is responsible for providing water to a large part of the Indian subcontinent and contains various flora and fauna.
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur
