Patterns in the sand along a frozen green river, that look a little like trees. Taken from a drone directly above.

It looks like an impact crater.
No, it's a mountain landscape, eroded over millions of years, which is also rich in mineral resources.

If anyone is friends with any Georgian air traffic controllers, buy them a nice bottle of wine. As guardians of pretty much the only narrow gap still available between Europe and Asia that avoids both Iran, the Gulf, Ukraine and Russia, they are under some substantial pressure.
