The slopes surrounding the basin of Barcelonnette are characterized by the presence of black marl, susceptible to erosion, badlands formation, and landsliding when saturated with water (also visible on the opposite slopes in the background of the scene). The Super-Sauze earth flow, which can be seen at the bottom of the picture, has evolved in a dip slope of mainly black marl (view from the scarp in NW direction). It is directly connected to the stream network, with the potential to produce debris flows affecting the main valley. Therefore, the situation is monitored continuously.
