Durango is in the high desert. We average around 18 inches of rain in a year, and most of that is from snowfall. The snow doesn't stick around for too long if it is on a south facing slope, but the north faces can hold it for a good while and there can be a decent accumulation. This heavily affects the zones of plant life on all the areas around town. The areas that are facing south are dominated by the pinon-juniper forests, and the northern aspects are inhabited by more shrubby types of plants. This leads to a great diversity of plant types.
