The high elevation ensures a cold, consistent climate that favours natural snow preservation. Storms frequently deliver generous totals, and the altitude keeps the snowpack dense and skiable throughout the core winter months. Season-long totals generally land between 6 and 10 metres, translating to a robust mid-winter base well above 2 metres.
