Hills and landscape
This region has several tall granitic hills which are famous for many short rock climbs, typically 1 to 2 pitches in length. Grades vary from 5.8 American to 5.11 American. It is home to some of the world’s oldest granite outcrops. Some of the interesting climbs are on the Wanakkal wall (“Gabbar ki asli pasand”, “Labor pain”), on the Rainbow wall (“UIAA”, “Kalia”), on Anna-Thamma (“Darkness at dawn”, “Black Diamond”, the name Anna-Thama means ‘elder-brother-younger-brother’ in Kannada).
Another well known hill is Ramadevarabetta. Along with Savandurga this was one of the shooting locations for David Lean’s A Passage to India. Small door like grottoes were made in the rock to resemble caves.It was also in this region that the path-breaking Hindi movie, Sholay, was shot.
Other famous hills in the region include the Revanasideshwara hill and Handigundi.
These hills have been threatened by quarrying and also plans to carve these hills into statues. The region is covered in scrub forest and is home to threatened bird species such as the yellow-throated bulbul and long-billed vultures.The hill is today one of the few locations in south India where long-billed vultures nest. The region is also home to numerous sloth bears.
The Closepet granites are a major geological feature of this region and are from the Lower Proterozoic era. This belt of rocks extend in the north-south direction in 50 km belt. This belt has younger potassic granites and is believed to separate two distinct crustal blocks of Archaean age. The block to the west has low grade granite-greenstone belts with iron-manganese ores and to the east are younger gneisses of granitic and granodioritic composition with gold-bearing schist belts.
