I completely forgot that happened. I used to live an a 10x10 cabin w/o water or electric. It was among other cabins some hippies built in the 70s. One was three stories (the octagon), and the pipe ran all the way up to the top, and it would get orange like that towards the bottom. The walls were just wood (not like your rock), so it was scary. That cabin burned down a few years after I left. I went back to my cabin a few years ago. It had finally crashed to the forest floor after over 40 years standing.

Thanks for the memory.

p.s. Snap of my cabin from 2023 here:
