Editor of the record: Patrick Cabrol.
Release Date: Thursday, January 20, 2011 .
Participants: Patrick Cabrol - DREAL, and Jean Pierre PLANTY - SCMNE.
Purpose: inventory of the karst limestone plateau Labruguière - RNA.
Time: 4 hours .
Work done: we worked mainly on the farm ROUMEGAS, and network COSTES Jean Marie (Loss Resse), and between In CRF, the Reclos, and Roumegas.
Conclusion of the day:
Jean Pierre showed me:
GENERAL CONCLUSION:
Small karst remarkable, important, very degraded, which threatens human security area. There should be studies on this last point, but this is not the responsibility of the cavers, who can not provide their comments to elected officials and administration.
Conclusion of the day:
- We enjoyed a beautiful sunny day, unfortunately a bit cooler, with a lot of wind.
- I thought I could work 2 or 3 times during a full day for this research, and finish everything, but the health of Jean Pierre did not allow me because of his difficulty walking. So I think doing half days, but it will anyway allow more time than I had expected. This work is indeed so.
- I did not expect at all to a karst of such importance. There may be some really penetrable cavities, but the potential is very large, perhaps unfortunately sometimes drowned in a gallery, or with boulders, hoppers.
- I was very surprised how many places as Jean Pierre told me, as having been subject to subsidence, lowering of construction, etc. ... He even said the houses which had to move the foundations because they overlapped with galleries, or areas very karstified. The road along the Thore, before the big sawmill, began to crack a few decades.
- We went to the Lost Arc, with the farmer's place. We have seen a collapse in the process of formation, 10 meters from this loss. The farmer told us quietly "it's new, it was not the last time. "Jean Pierre also tells me that some day he was looking for mushrooms in a close, and he was followed by a cow, he bends down to take a fungus, when he turns around, the cow is gone 3 to 5 feet below! It took a shovel and straps to pull her out; ......
Jean Pierre showed me:
- sinkholes that were cleaned of tons of car carcasses, mattresses, stoves, etc. ... They are now invisible because resealed.
- an important series of sinkholes that have been filled with rubble. For example, today there is a substantial narrowing of a valley full as Roumégas.
- many holes, sinkholes, etc. .... that are resealed by farmers as and when they are formed.
GENERAL CONCLUSION:
Small karst remarkable, important, very degraded, which threatens human security area. There should be studies on this last point, but this is not the responsibility of the cavers, who can not provide their comments to elected officials and administration.
