Found big pipes running through the woods. What are they??

A lot of aluminum was used pre-plastic post war. Looks like aluminum to me. Not really able to tell from the pics. Resembles galvanized too somewhat.

Wow! Aluminum water pipes. Well, I guess if you are going to replace them in 5 years...

Maybe a mix of different metal types?

Aluminum rusting? Odd.

galvanized steel would be more likely I think. Cheaper by a fair bit, and it will eventually rust, especially if scratched through the plating. A magnet will tell you.

The other thought I had was maybe a still. If the pipes tap into a spring or a stream at higher elevation it may be used to run cold water down to a condenser. Seems a bit extensive for that though.

My guess: still. 100%

Have you followed the pipes to see where they come from or go? Maybe find someone with a drone.

or painted.

The way the coating is flaking, it's coming off more like paint than plating.
