Snow and Weather Conditions
Sierra Nevada storms deliver heavy, moisture-rich "Sierra cement" snowfall. When cold fronts align, the result is deep dumps that can exceed a metre in a single storm cycle. 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. Most winters deliver 6-10 metres of cumulative snow, compressing into a 2-metre-plus base by the middle of the season.
