Grotte du Scorpion

A few tens of metres from the grotte du Scorpion (Scorpion Cave) is an impenetrable fissure that blows particularly cold air, 7.1° C in June 92 for 19° C outside, at a flow sufficient to be felt three metres lower, in a very intensely fractured zone where internal exploration has not discovered a typical conduit.

If the temperature suggests a significant height difference, the fissure (whose coordinates are not provided) does not seem the best means of reaching it; the contrast is all the greater since a few tens of metres away lies precisely the present grotte du Scorpion (Scorpion Cave).

Moreover, there is more than one degree of difference between the two air currents, which is significant enough, given the small height difference between the two entrances, to conclude that the potential networks are independent, or at least as to the origin of the high point[ref]Inventaire CDS04 > "Grotte du Scorpion" (number 04.MUA.001): https://speleo.ronaldpoell.eu/Speleo/04/SpPub/04MUA/04MUA001.html[/ref].
