Before
jumping into my journeys and experiences in the Himalayas, although it may not
be new for you, I am going to present a brief introduction of the Himalayas;
especially the origin and evolution!
A quote, my favorite one, about the Himalayas
by a famous Nepalese Geographer which, I always appreciate and adore:
“IT WOULD BE
MORE REALISTIC TO CONSIDER MOUNTAINS AS DYNAMIC, CERTAINLY NOT FRAGILE”
– Dr. Harka Gurung (2004).
#1. Himalayas: The Youngest Mountains in the World
According
to Bob Stoddard, Professor of Geography at the University of Nebraska-Linkon,
US; the origin of the Himalayas dates backs some fifty million years ago when
the two continental plates that form the cores of peninsular India (Gondwana
land) and central Asia (Laurasia) began squeezing together.
Previously these huge sections of earth surface were separated by shallow sea,
which was receiving the eroded sands and muds that were being dumped into it by
rivers emitting from the land masses. As the two continents moved together,
they squeezed and buckled these relatively soft earth materials into gigantic
folds. As these earth materials became pushed higher, they formed the ranges of
mountains – now called the Himalayas. Actually this mountain-building process
is still occurring as the mountains continue to rise each year.

The
evidences are: one is the limestone beds that compose part of the highest
mountains, such as Mt. Everest (Sagarmatha) because the origin of limestone was
the former shallow sea. And these days those sedimentary rocks are way far from
the sea level standing as a water tower. Next evidence: the fossils found on
the slopes of the mountains (e.g. the Ammonites i.e. Saligram Sila found in
Kaligandaki valley, Mustang, Nepal) indicate life that once existed in seas
before the mountains arose.
