"This feature is shaped like the Roman numeral VI. Each arm of this feature is a trench that is about 2 metres wide, 2 metres deep and more than 100 metres long.

Could this have been used for studying astronomy?

"The Tropic of Cancer passes through Kutch. So if this structure is man-made, it is likely that the slope of the hillock was utilised for making certain astronomical calculations in the past," explains the geologist.

I wonder if the scientists have considered the possibility of this very long and narrow trench just being an abandoned drainage construction project? Possible, no?

Any of you guys ever come under the spell of this terrible book in high school?
