On 16 December 2008 at 11.15 am, a large scale avalanche started in the upper watershed of the Fougeret couloir and ended its course in the hamlet of Cialancier, in the municipality of Saint Etienne de Tinée. A house was destroyed and two others were damaged. Luckily, there were no casualties. This article describes how to design and build an avalanche protection dam.
