Nice work, longbomb. I like he way the surface expression , imaginary and otherwise, is leading in that direction. It is also very possible that veins that are not visible on the surface could be the feeder conduits for a localized system. Or not...LOL!

But in reality, these large systems require their own plumbing,as it were, and just because you don't see the pipes on the surface doesn't mean they don't exist at depth.

Only time will tell...guess I'll be around to find out!
