Each mountain range around the world has it’s own type of climate, which dictates the type of snow found each winter. The Rocky Mountains are famous for light powdery snow, whereas the Costal Mountains of British Columbia are know for their big dumps with heavier density snow. In the Andes Mountains of Argentina & Chile, there is a great variation in the type of snow that falls each season, as there is a big difference in elevation, temperature, & location. In the northern Andes the climate is very dry as it is a high mountain desert, so here you should expect colder dry snow to that found in Patagonia, where elevations are lower. Patagonia typically sees quite a bit more precipitation, as it is a wetter climate, & with warmer temperatures.
