The northern end of the range continues as isolated hills and
rocky ridges into Haryana state, ending in Delhi. The well-known
Delhi Ridge is the last leg of the Aravalli Range, which cross
through South Delhi and terminates into Central Delhi where
Raisina hill is its last extension. It is one of the world's
oldest mountain ranges. It dates back to a pre-Indian
subcontinental collision with the mainland Eurasian Plate. The
southern end is at Palanpur close to Ahmedabad, Gujarat. The
highest peak is Guru Shikhar in Mount Abu in Rajasthan. Rising
to 5650 feet (1722 meters), it lies near the south-western
extremity of the range, nereby the border with Gujarat District.
The city of Udaipur with its lakes lies on the south slope of
the range in Rajasthan. Numerous rivers rise amidst the ranges
together with the Luni River, the Banas River, the Sakhi ,Sabarmati,
and the Sahibi River.
Old fold mountains are portrayed by having stopped growing
higher due to the cessation of upward thrust caused by the
stopping of movement of the tectonic plates in the Earth's crust
below them. In ancient times they were extremely high but since
have worn down almost completely by millions of years of
weathering. In contrast, the Himalayas are continuously rising
young fold mountains of today. |
