The photo above shows the results of a paleo-landslide near Lillaz village, in the Aosta Valley of Italy. This translational slide was likely triggered at the end of the last ice age. A huge mound of rocks and debris piled up at the base of the mountain largely consists of gneiss boulders. Early season snowfalls cap the higher summits of the Italian Alps in the background at left. Photo taken on October 19, 2014.
