The Marin Independent Journal reports (http://bayareane.ws/2icWjHK) the driver was identified as 20-year-old Jose Hernandez.
Marin County fire battalion chief Bret McTigue says the wreckage was discovered Monday morning in the Hicks Valley Area.

Most of Reno's downtown bridges reopened Monday after Truckee River flooding subsided. But a number of flood-damaged roads remained closed, including a stretch of State Route 446 near Pyramid Lake north of Reno where a washout left behind a 50-foot-deep crevasse in the road.
Emergency crews in Reno and Sparks are trying to clear flood debris to make way for snowplows the next two days as another major winter storm moves into the Sierra.
Flooding shouldn't be a problem, but the National Weather Service has issued a winter storm warning in effect until 4 a.m. Thursday for the Lake Tahoe area where a backcountry avalanche warning also is in effect.

Sacramento River levels have increased so much that state officials plan to open the weir located four miles upstream of Sacramento's Tower Bridge for the first time in more than a decade.
The weir is a barrier that includes 48 gates that must be opened manually with a long hooked pole to protect the city from floodwaters. Once opened the water is redirected west to the Yolo Bypass.
The gates are opened when the river levels are 30 feet and rising.
The California Department of Water Resources says that as of Monday afternoon the river is at 27.7 feet.
The weir was last opened in 2005.
Nevada Gov. Brian Sandoval says officials are checking to determine the severity of damage to property, bridges and roads following heavy rains and flooding.

He says regular emergency vehicles are being used.

Cars later used the massive tunnel, but more recently it has hosted only hikers.
Park volunteer Jim Allday of Arnold says the tree shattered as it hit the ground.
There was no immediate word on what caused the tee to fall, but the Chronicle reports that it probably had to do with the tree's shallow root system and the inundation.
