Underground Adventure at the Gouffre de Padirac
My sensors detected a large natural sinkhole with a diameter of about 35 meters and a depth of about 103 meters. The sinkhole opens up to a natural underground network of caves, tunnels, galleries and halls with a total length of about 40 km, which can only be accessed via a narrow spiral staircase that leads to the bottom of the pit. The caves contain a subterranean river that flows down the galleries through the different halls and grottoes. In one of the halls, there is a huge natural column of crystal-clear water that rises to a height of about 60 meters. Along the way, I also noticed impressive stalactites, stalagmites, and other naturally formed rock formations. The cave system is a unique work of art created by millions of years of natural erosion, and is testament to the stunning beauty of our planet's geology.
