ABSTRACT:
An attempt has been made to predict the life of Lake Nainital, a natural lake located in
the Kumaon Himalaya with early large human settlement around it. Sediment
accumulation rates estimated by dating the lake sediment cores employing 210Pb and
137Cs dating techniques have been used for the purpose. The sediment accumulation
rates estimated by radioisotope techniques are comparable to the rates obtained by the
sediment balance method using the suspended sediment data. The estimated useful life
of the lake is about 2,200 years, which is much higher than the results obtained by
earlier investigators who used short-term bathymetric data. In the present study, long
term ( 46 years ) annual lake sounding data have also been analyzed. Large bidirectional
variations in the annual bathymetry imply that major errors are associated
with the lake sounding data that led to the under-estimation of the life span of Lake
Nainital by earlier investigators
Population : 6,00,000 ( 1995 ) 
Adventure on the road is never short on the beautiful Trans-Himalaya drive of over 970-kms, through four mountain passes, promising a panorama of a cultural and scenic diversity unsurpassable anywhere. The Buddhist monasteries of Drepung, once the largest; the Jokhang- a spirtual centre, and the awesome palaces of the dalai lama. Norbulingka or the Summer Palace and the Potala - the Traditional Seat are some of the highlights of visit. 
This region accounts for about 64% of total land area. It is formed by the Mahabharat range that soars up to 4,877m and the lower Churia range. 
Hinduism and Buddhism constitute two major religions of Nepal. A remarkable feature of Nepal is the religious homogeneity what exists, particularly between the Hindu and Buddhist communities. Apart from the Hindus and Buddhists, Muslim from the third largest religious group.
Himalayan range covers the entire northern part of India, nestling five major states of the country within it. The ancient Indian pilgrims who have travelled in these mountains since time immemorial coined a Sanskrit word for the Himalayas meaning “Abode of Snow”. 
Jammu and Kashmir are really three regions: the foothill plains of Jammu; the lakes and blue valleys of Kashmir rising to alpine passes, the high altitude plains and starkly beautiful mountains of Ladakh, which lies beyond those passes. It's enough to move one to poetry. Srinagar is Kashmir's summer capital and Jammu, the winter capital. Among the most attractive part that this Indian state has is the adventure oppurtunities that can be seggragated into trekking, mountaineering and Trans Himalayan Jeep Safari.
Himachal Pradesh is the land of snow, lofty peaks, cascading streams, alpine meadows & lush fruit-laden valleys. Many parts of the Himachal state have a distinctly Austrian look with conifer-clad mountains, chalet-like huts with overhanging balconies and serene blue valleys watered by snow-fed streams. Shimla the capital of Himachal Pradesh, is still very much a Raj township in appearance and atmosphere. 
A former kingdom , Sikkim is now the 22nd State of India. It is rooted to the Himalayan Massif like a scale on the neck of a Dragon. One of the smallest states of India, it is bounded by Nepal to the west and Bhutan to the east; by the Tibet Autonomous Region of China to the north and northeast and by West Bengal to the south. 
Nepal is known as a true Himalayan Kingdom, reason being this country contains nine of the world's fourteen highest peaks. The Himalayas cover three fourths of the land in Nepal. This country is home to some of the highest, rugged, remote and most difficult terrain in the world.
