Caves and chasms: can you tell the difference?

The entrance toa cave develops mainly on a horizontal plane. Often the caves are current or ancient resurgences (water outlets) which drain the infiltrated water from the upper networks.

A hole, on the other hand, begins with a vertical section that requires the use of apparatus. It will open up especially on the plateaus. It may be a sinkhole (a hollow widening and deepening by chemical and mechanical erosion) which ended up joining an underground network already in place. But it is often a collapse of the “ceiling” of a river or an underground cavity.

One thing is certain and common to chasms and caves: it is strongly recommended to bring a little wool before visiting them. (13° to 15° all year round).

Caves and Chasms in the Lot department near Brive: 

Karst Relief

Do you see the difference ? Come on, let's make things a little more complicated for you. Did you know that in certain regions the terminologies are different? Thus a chasm will be called “aven” in the Causses, “scialet” or “pot” in the Vercors. The inhabitants of Devoluy will speak of “chourum”.

To shine with family or friends, and plunge your interlocutors into the abysses of the well of your knowledge, talk to them about “karst reliefs”. Located on the borders of Quercy, Périgord and Limousin, our destination is based on limestone plateaus whose cavities created by physical and chemical erosion are thus named.

Stalactite or stalagmite

These natural constructions are often embellished with magnificent concretions linked to a very long chemical phenomenon again: the crystallization of carbonates dissolved in runoff water.

Between Falling StalacTites and Rising StalagMites, between dizzying drapes and column of calcite iridescent with precipitates of mineral salts, wonder is offered to our gaze... but be careful, we only touch with the eyes, these natural sculptures are so fragile and to preserve.

But it has been a while since humans got into the habit of visiting these places full of mysteries and hidden beauties. Our ancestors even tagged them... bequeathing us grandiose and mind-blowing works that inform us about our origins. We can thus evoke 20.000 years of traces of human presence in our valleys…

But perhaps the simplest thing is to go directly to visit them?
