The state of Haryana is bounded by Uttar Pradesh in the
east, Punjab in the west, Himachal Pradesh in the north and Rajasthan
in the south. The Union Territory of Delhi juts into Haryana and is encompassed
by it on three sides. The south west of the Haryana is dry sandy and barren.
The natural boundaries are: the Shivalik hills in the north, River
Yamuna in the east and river Ghaggar in the west. The south western boundary
is provided by the range of Aravalli hills, which run through southern
Delhi and the Gurgaon district up to Alwar. There are some high ridges
running from the north-west to south-east with numerous spurs branching
out in all directions. These hills are known as the Morni and Tipra ranges.
They belong to the outer ranges of the Himalayas.
