Though strik­ing­ly sim­i­lar to the DC com­ic hero’s head­quar­ters, this place is ANYTHING but peace­ful. Locat­ed in North­ern Mex­i­co in close prox­im­i­ty to a large mag­ma cham­ber, the col­lect­ed heat alone has enough inten­si­ty to melt your face right off. The tem­per­a­ture in the main cav­ern fea­tured above exceeds 50°C or in Amer­i­can terms, 122°F.

The climbers above wear spe­cial cool­ing suits in order to walk on top of these giant crys­tals.  These suits are essen­tial­ly huge packs of ice, engi­neered to keep the body cool dur­ing the treks into the cave.  Even with these suits, the explor­ers end up drenched in their own sweat, mak­ing this jour­ney exhaust­ing and time con­sum­ing, but absolute­ly worth it.
