This is the old powerline. It was buried between 2014/2024. I can see them in 2014 pictures. Not in 2024 ones.
I remove the poles and let the line as power:cable. By default, it is assumed as underground.
Only one part at West is still overhead.

Not sure underground powerline is exactly at the same place (more likely it is close). But we can not dig to find them :).

What do you think?
