This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Yeah thats exactly the issue I ran into. I started googling stable soil temp to confirm what I thought, and rapidly ran into a lack of answers lol. Any data I could find for free on websites didn't seem to go very deep.
In terms of depth of the Qanats, yeah I was wondering the same. Without any modern tools I'm not sure how deep they would be willing to dig out (although I bet it's easy digging in Iran, likely sand/dry dirt vs. clay and sopping wet boggy soil).
I am at work but I'll see if I can dredge up info on Qanat depth
