The family then drove to Napa County and found a big surprise at the summit of Mt. St. Helena, snow in Robert Lewis Stevenson State Park.

"I'm actually from Santa Rosa, this is new to me to live in an area that snows," said Molly Contreraz.

Caltrans snowplows were busy at work dropping sand on Highway 29 to prevent cars from spinning out.
