A Napa woman who was driving through Graton early Saturday morning lost control of her car and spun off Highway 116, taking out about 60 feet of vineyard fencing and two apple trees before slamming into a light pole north of Occidental Road, the CHP said.

Officials said Kellie Brett, 29, was injured in the 1:54 a.m. crash but walked away and called an Uber to take her to a Napa hospital.

Authorities, unable to locate her anywhere near the crash site, found her nine hours later at Queen of the Valley Hospital, CHP Sgt. Josh Kolstad said.

Graton firefighters said Brett may have been traveling too fast in heavy fog when she lost control of her southbound car on a stretch of highway near Peachland Avenue, north of Occidental Road.

Her 2013 Volkswagen Golf was spinning as it struck the wooden fence. The force of the impact was enough to break apart the front end and throw the engine block from the wreckage before it caught fire, emergency officials said.

The crash remains under investigation, Kolstad said. No citation or arrest was reported.
