Recent storms will ensure a long ski season at Lake Tahoe area resorts. Boreal and Soda Springs Mountain Resort extended their season by seven days and is expected to close April 22. Heavenly Ski Resort will also close April 22, and Kirkwood Mountain Resort will close April 15. A break in the weather over the past weekend allowed skiers and boarders and opportunity to get up on the hill, and operators are expected a burst of activity this week, as many schools are on spring break.
