The closest I have come to a Mandelbrot Set in nature. 13,000 feet. Fuji Velvia 50. One of my absolute favorite shots. I took a 4x4 truck as far as I could (about 2pm) and then hiked from 2pm to 4am, 4000ft to 13,000ft, mostly in the dark, to reach the spot. The goal was Sawtooth Peak, but I ended up a few miles away. I put on my wetsuit, waited for sunrise and climbed in. The water frozen at the edges. I took six shots and got out.
