Hills of Peninsular India
Aravali Range
• They are aligned in north-east to south-west direction.
• They run for about 800 km between Delhi and Palanpur in Gujarat.
• They are one of the oldest (very old) fold mountains of the world and the 
oldest in India. {Fold Mountains – Block Mountains}
• Now they are relict (remnants after severe weathering and erosion since 
millions of years) of the world’s oldest mountain formed as a result of 
folding (Archaean Era).
• At the south-west extremity the range rises to over 1,000 m. Here Mt. Abu 
(1,158 m), a small hilly block, is separated from the main range by 
the valley of the Banas. Guru Sikhar (1,722 m), the highest peak, is 
situated in Mt. Abu.
• Pipli Ghat, Dewair and Desuri passes allow movement by roads and 
railways.

Vindhyan Range
• It runs more or less parallel to the Narmada Valley in an east-west 
direction from Jobat in Gujarat to Sasaram in Bihar for a distance of 
over 1,200 km.
• The Vindhyas are continued eastwards as the Bharner and Kaimur
hills.
• This range acts as a watershed between the Ganga system and the 
river systems of south India.
• The rivers Chambal, Betwa and Ken rise within 30 km of the 
Narmada.

Satpura Range
• Satpura range is a series of seven mountains (‘Sat’ = seven and ‘pura’ 
= mountains)
• It runs in an east-west direction south of the Vindhyas and in 
between the Narmada and the Tapi, roughly parallel to these rivers.
• It stretches for a distance of about 900 km.
• Parts of the Satpuras have been folded and upheaved. They are 
regarded as structural uplift or ‘hor s t ’.
• Dhupgarh (1,350 m) near Pachmarhi on Mahadev Hills is the highest 
peak.
• Amarkantak (1,127 m) is another important peak.
