DONNER SUMMIT (CBS13) – Two Lake Tahoe ski resorts will be open this week after the first storm of the season blanketed the Sierra in fresh snow.

Boreal Mountain Resort announced that it will open its ski and snowboard season on Friday.

The resort will operate one lift from 9 a.m. to 9 p.m. It’s the fourth year in a row that Boreal has opened for skiing and boarding in October, the resort said.

Boreal will operate the Castle Peak Quad chairlift offering access to one run featuring multiple terrain park features, it said.

Boreal plans to operate through the weekend and will assess conditions on Sunday to determine a mid-week operating schedule.

Squaw Valley will be open on Thursday for a special fundraiser event from 10 a.m. to 2 p.m. Lift tickets are $20 and all proceeds benefit the Squaw Valley and Alpine Meadows Ski Team Foundation.

Squaw’s planned full opening is scheduled for Nov. 21.
