[Note Guidelines] Photographer's Note
The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India (between 17–24N, 73–74E) and one of the largest volcanic features on Earth. They consist of multiple layers of solidified flood basalt that together are more than 2,000 m thick and cover an area of 500,000 km². The term 'trap', used in geology for such rock formations, is derived from the Swedish word for stairs (trappa, or sometimes trapp, referring to the step-like hills forming the landscape of the region.

The Deccan Traps formed between 60 and 68 million years ago, at the end of the Cretaceous period. The bulk of the volcanic eruption occurred at the Western Ghats (near Mumbai) some 66 million years ago. This series of eruptions may have lasted fewer than 30,000 years in total. The gases released in the process may have played a role in the Cretaceous–Tertiary extinction event, which included the extinction of the dinosaurs.

Before the Deccan Traps region was reduced to its current size by erosion and continental drift, it is estimated that the original area covered by the lava flows was as large as 1.5 million km², approximately half the size of modern India. The present area of directly observable lava flows is estimated to be around 512,000 km².

The release of volcanic gases during the formation of the traps "contributed to an apparently massive global warming. Some data point to an average rise in temperature of 8 °C (14 °F) in the last half million years before the impact at Chicxulub".

Subhash,

Very interesting photo. Thanks for the note—otherwise I wouldn't have known what I was looking at.

I did a variation of your photo as a workshop—hope you like it.

TFS,
Michael

hello Subhash

to tell you the truthu i have dizziness of everything that is higher,
and what a superb POV you have here, your photo it is
giving me a dizziness at this moment, i love the warm
colour tones of the mountain's rocks, TFS

Asbed

yet another very educating shot, apart from the beauty, Ranjan.
Very well done!

Hi Subhash,

A fascinating shot and excellent notes. I was wondering about the name Deccan Traps but you explained it well. Another excellent picture of something very few of us will ever see for ourselves.

This image, no doubt, illustrates very effectively the nature of these geological formations that took place millions of years ago, Dr Subhash.
Thanks for appending an erudite note with the picture. It really helps in understanding how the Deccan Traps have undergone stages of transformation since they were formed.
Thanks and regards.

Hi Subhash,
Nice to see some more landscapes on TN i.o. all the birds and insects. You've got yourself a very interesting photo of a very interesting rock formation. It looks similar to what you can find in the Rockies, but then again vulcanic eruptions are the same all over the world.
TFS,
Niek

Hello Subhash,
An amazing 'trappa'-like rock formation of the Deccan Traps nicely captured to show the formationa as well as the sand-like result of erosion.
The POV and composition are excellent as well as your great informative note.
Thanks and best regards,
Ivan

Dear Dr. Subhash Ranjan,
I lived in India as you know but I was totally unaware of this MARVEL.
Thanks for NOT ONLY sharing this image but for "EDUCATING" us, mankind.
Friendly greetings from,
Mario.
