Landslides caused by beavers
In Switzerland a section of the A1 motorway close to Courgevaux in the canton of Fribourg was closed by a landslide triggered by a beaver. Thelocal.ch has the details:
Several tonnes of earth and rock covered the roadway early in the morning and it took a crew with earth-moving equipment until the evening to clear it up, police said. The beaver had blocked a stream running parallel to the motorway. Pressure from the water burst a retaining wall, triggering the landslide, police said. There was no information on what happened to the beaver.
There is also an image of the debris:-
Perhaps surprisingly this is not the first time that beavers have been responsible for landslides. Back in July, a landslide in Likely, British Columbia in Canada was caused by the collapse of a beaver dam. This landslide damaged a road, causing 14 properties to be cut off. Meanwhile, back in July 2014 beavers were initially blamed for causing a landslide in North Okanagan, also in BC, although after putting up a spirited defence they were subsequently vindicated.
