They simulated three different avalanche terrains on a flat board, and used flour, salt, sugar, and potato flakes to simulate varied snowpacks. As they increased the angle of the board, they measured the angle of incline as they observed what was happening to the different layers. They looked for slab and loose avalanches and reported at what angle they occurred as well as the distance of the slide. They used their data to derive generalizations about snowpack and incline in nature.
