Sonora man dies in ATV accident

A Sonora man was fatally wounded when he was ejected from his all terrain vehicle at the bottom of a steep hill.

William Robert Clark, 47, was driving his 2007 Polaris ATV through a Stanislaus National Forest route designed for off-road vehicles.

He was traveling northbound around 7:30 p.m. when he passed two ATV drivers, according to CHP officer Michael Remmel.

Due to his high speed, Clark failed to negotiate a right curve.

His ATV flew off the road and Clark went tumbling down a rocky mountainside, winding up on the shoulder of the forest route.

Clark was wearing a helmet at the time but died as a result of head injuries.

Remmel said Clark was a correctional officer at the Sierra Conservation Center, a prison in which inmates are trained to work on crews for Cal Fire.
