Choranche Cave
The cave of Choranche, also called cave of Coufin-Chevaline, is located in the department of Isère (department), Isère, near Choranche in the Vercors Regional Natural Park and in the Vercors Massif, France. Located at the edge of the massif, its road access is either via the A49 motorway (France), A49 Grenoble - Valence motorway, or by a road entering the massif, near Grenoble. The entrance to the cave is at the foot of the cliffss of Presles, Isère, Presles, forming a natural cirque bordering the Coulmes plateau in the Bourne gorge. In November 2014, the Choranche cave obtained the "Quality tourism" mark. History Coufin Cave Oscar Decombaz, on , explored up to the wet vault. In 1949, the defusing of the latter allowed Roger Pénelon and Sage to access Gruyère. In 1954, the Cyclops group went up the Mat waterfall () and stops at the foot of the large waterfall.

Flowstone
Flowstones are sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave. They are typically found in "solution caves", in limestone, where they are the most common speleothem. However, they may form in any type of cave where water enters that has picked up dissolved minerals. Flowstones are formed via the degassing of vadose percolation waters. Flowstone may also form on manmade structures as a result of calcium hydroxide being leached from concrete, lime or mortar. These secondary deposits created outside the cave environment, which mimic the shapes and forms of speleothems, are classified as "calthemites" and are associated with concrete degradation.Smith, G.K., (2016). “Calcite Straw Stalactites Growing From Concrete Structures”, Cave and Karst Science, Vol.43, No.1, P.4-10, (April 2016), British Cave Research Association, ISSN 1356-191X.
