We had an early start to the ski season around here this year. Snoqualmie is the lowest elevation and is still waiting for enough snow, but everyone else is open. Years ago I made a chart of the opening dates on the Seattle PI blog. I’ve updated it this year with the help from some fellow skiers at work.
