Actually it looks like the "Hellhole" cave in the video I posted above is one located in Santa Cruz California. https://www.adrex.com/en/articles/earth/speleology/hell-hole-santa-cruz-california-united-states/ Caves are fascinating but give me a 0.5 difficulty rating on a scale of 1 to 10 please! :wacko: Me three... Going up the McPlayland at the McDonald's closest to me would be the most difficult thing I'd ever want to attempt this side of the Rapture Ok so I do like caves, the large open caverns that is …. :mdrmdr: The wee little spaces are not designed for anyone except the wee folk…. :mdrmdr: I have seen some beautiful sites and always wonder at the delicate design of the Father. That cave is a shear horror show with all the bells and whistles. Yohanan you are welcome to it sir, enjoy the self made coffins - ugh! Here is one for you I saw the other night — think gypsum mines, wide open spaces, but danger city to the max - enjoy https://cen.acs.org/physical-chemistry/geochemistry/Naicas-crystal-cave-captivates-chemists/97/i6 55 C = 131 F Add in 90% humidity. *Ow* You can't even cool yourself by sweating in those conditions and you can only be in there for 10-15 minutes maximum. Those giant gypsum crystals look amazing, though. I look forward to finding places like that in eternity with a glorified body that can handle it.
