The Sierra Avalanche Center, a Truckee-based nonprofit that provides free daily avalanche forecasts for the Tahoe region, is holding fundraisers at several Tahoe-area resorts in the coming weeks. Skiers and snowboarders can purchase an all-day lift ticket to Northstar Jan. 13 for $40 (it's $74 for a regular all-day adult pass); tickets to Mt. Rose Feb. 13 are available for $30 (regularly $48). There will be similar deals at Homewood March 2, Sugar Bowl March 7, and Alpine Meadows March 30. These special tickets are available online only at sierraavalanchecenter.com. All the proceeds from ticket sales go straight to the avalanche center, providing funding for staff salaries, much-needed equipment, and daily operational expenses.
