- The Bommayapalayam Canyon is part of a range of ravines skirting the Auroville bio-region.
- They were formed over the centuries of downcutting by the water currents of the monsoon rain ferrying topsoil and rock fragments to the Bay of Bengal.
- The Tamil Nadu government plans to protect the canyon, declaring it a geo-heritage site.
- The ravine, a narrow, deep valley with steep sides, has an average height of 7 metres, a width of 30 metres.
- It dates back to the Miocene age estimated to be in the range of 23.03 to 5.33 million years ago.
- The canyons are the cumulative outcome of years of soil erosion, rather than any tectonic activity.
