Huge snow storms in March saved the season for Lake Tahoe ski resorts


Huge snow storms in March saved the season for Lake Tahoe ski resorts - San Francisco skiing | Examiner.com

Sugar Bowl ski resort received more than 200 inches of snow and had many powder days in March were frequent throughout the region.
Still, the snow totals are not even close to last year’s record season at many resorts. A year ago, Sugar Bowl had 802 inches of snow and was sending skiers and riders down its trails on Fourth of July! This year the total was 324 inches by April 9.

Heavenly ski resort was also pleased to finally shut down its snowmaking operation in March when 110 inches fell. Yet season totals are poor. The resort has received 247 inches of snow this year, well off the mark of 529 a year ago
