At an altitude of 1,565 m, the climate is harsh: weather conditions are the same as they would be at 2,000 m elsewhere, with only four “frost-free” months a year. Winds of above 60 kph blow on 265 days a year, and the average annual temperature is 4.8°C. Trees do not have enough time to complete their life cycle. Local plant formations are those of the montane zone: subalpine short-grass prairies.
