rocks

as we drove through andhra pradesh, we saw granite rock formations that looked as though they had been built by hand. quoting from one website:

andhra pradesh is endowed with spectacular rocky formations, which at many places, are simply awe-inspiring. they are indeed a natural wonder of stony ridges and hillocks shaped into picturesque balancing forms through millions of years of weathering and wearing. the deccan plateau, that is the vast expanse of peninsular india, south of the vindhyas and composed mostly of grey granite, is among the oldest and hardest rock formations in the world. geologists date these rocks to a period 2,500 million years ago. that is the time when the earth’s crust solidified. molten magma then pushed upwards from the interior and hardened under the crust into domes and sheets of granite. then horizontal and vertical cracks developed and slowly the top layers of the crust eroded and these very hard granites were exposed. they weathered over millions of years into their present forms – resulting in the bizarre, awe-inspiring, wonder-striking and almost man-made-kind-of formations.

there is a society to save rocks that is dedicated to preserving these formations.

(in response to a comment i received, i should note that this is actually a necessary type of organization. there are stonecutting companies that will level entire hills of this size for the raw building materials, if they get the chance. a fellow photographer showed me a field where a hill on which gandhi had spoken had been cut away; nearby was a hill with a huge slice cut out, like a birthday cake.)
