Odd feature at Edge of Indian Subcontinental Shelf

I chanced upon this. It almost looks like the remnant of a bridge extending out to a plaza. But the "bridge" is nearly 2 miles wide, and the "plaza" is nearly 4 miles by 4 miles. The pixilation is probably enhancing the bridge-like appearance. I'd be much more likely to consider this something actually archeological in nature if I knew more about the Vedic texts and the ancient sites it describes. What do you think?

Welcome to the forum,  sonicsculpture!

Please attach the coordinates for your location (KMZ-File). Then we can look at that exactly.

But I think that's the sonar track of a ship. So a case like in this thread.

The different methods  (satellite systems and  ship sonar) of  representing the depths use  a different false colour  system.  Most of the data is satellite, and is very low resolution, and very low accuracy, and depth shown as the gradual darkening of the blue.

Ship sonar traces form  lines and blocks inside the satellite data.  The increased resolution of the ships sonar trace, showing a texture, is a clue that its not the same system.. The boundary  is merely due to the mismatch in the false colour system . Maybe Google could colour the  surface/subsurface sonar traces in red or something, and allow it to be turned off ? Or off by default and customisable colour.. ?
