Nepal

One can probably say that Nepal is as old as the Himalayas, when a great lake filled the Kathmandu Valley. One legend holds that this lake was drained by a thunderbolt thrown against the walls of the Valley by the Hindu god Krishna. Another claims it was drained by the patriarch Manjushri as he wanted to get a closer look at a Swayambhu or Adhi-buddha, the beautiful lotus flower resting on the lake.

But the recorded history of Nepal does not start until around 800 BC, with the beginning of the Kirat Period. After that was the Lichhavi and Thakuri Period, followed by the Malla Period and finally the Shah Period.

Nepal is of roughly trapezoidal shape, 650 kilometres (400 mi) wide and 200 kilometres (125 mi) broad, with an area of 147,181 square kilometres (56,827 sq mi). Nepal is commonly divided into three physiographic areas: the Mountain, Hill, and Terai Regions. These ecological belts run east-west and are bisected by Nepal's major river systems.

The Terai Plains bordering India are part of the northern rim of the Indo-Gangetic plains. They were formed and are fed by three major rivers: the Kosi, the Narayani (India's Gandak River), and the Karnali. This region has a hot, humid climate.
