Some fear that a new subsidence will occur and block the river. “You see a lot of trees coming down from the mountain and the sand coming up the bottom of the river. So, let's say it could have a big impact if everything tumbled into the river and all of Belle-Vallée was flooded," observed Frédéric Boisclair, promoter of tourist accommodation in Belle-Vallée located on the bank opposite the scree. .

Last Friday, Civil Security dispatched a technician to the site who examined the site, in particular with a drone. An engineer, expert in ground movement, will also go there to assess the risks.

At first glance we do not believe that there is reason to be alarmed. There is no clue to predict a new dropout. “There have been some moves. These movements are not major. These are movements that seem to be normal in the stabilization of an event that occurred perhaps a year and a half or so ago and which has been documented, ”explained Sylvain Gallant of Civil Security. No dwellings or buildings are in the risk zone at the top of the escarpment.
