PHUSICOS: Unstable till slope at Santa Elena

The slope at Santa Elena has been pointed out as one of the high-risk locations along road A-136, which is an important route between Spain and France (road RD-934 in France). The problem is erosion and instability in a steep slope, cut in a thick till deposit. This is an end moraine formed by the confluence of two valley glaciers during the last glaciation, the 'Würm', which in the Pyrenees ended ca. 16000 years BP. The visibility at the site is low, the speed often high, and the risk is mainly connected to rocks lying in the road. Let's have a look on the works developped by PHUSICOS and listen some explanations from involved stakeholders.
