A San Rafael man who built an illegal bike trial on federal land in 2001 is in legal trouble again – this time for carving a trail in China Camp State Park, authorities said.Michael Philip More, 54, was charged Thursday in Marin Superior Court with willful or negligent destruction or removal of plants and dead wood, diverting or obstructing the natural flow of a stream, resisting a peace officer and allowing a dog to roam off-leash in a restricted area, prosecutors said.

More is accused of digging an illegal bike trail into a hillside, hacking down tree limbs and constructing rock paths through two drainage ditches, authorities said. The quarter-mile trail is at the end of Robinhood Drive in San Rafael’s Glenwood neighborhood, which borders the state park.

The cost of repairing the damage is estimated at $20,000, said Kathryn Mitchell, a senior county prosecutor.

Dave Gould, the superintendent overseeing state parks in Marin, said the damage to the natural resources was “significant.”

“It looks like chainsaws were used and trail-building tools to carve out the hillside,” he said. “This isn’t where 15 people walked up and down the hillside and you can see their path – this is an attempt to construct an illegal trail.”

More, who could not be reached for comment, has pleaded not guilty. His attorney, Patrick Ciocca, said More would be “loathe to engage in a public discussion” about the allegations while preparing his defense.

“It would not be beneficial for him to enter into a public dialogue,” Ciocca said.

Park rangers received a tip about the trail in March, when a resident noticed unusual activity in the area. A ranger investigating the trail found More at the scene, and More allegedly tried to flee.

More was cited, but not arrested, while prosecutors reviewed the case. He is scheduled to be appear in court on May 9.

Alex Burnham, president of the San Rafael-based Access4Bikes advocacy group, said he is concerned that the case will tarnish the entire bicycling community and inflame tensions between cyclists and noncyclists. The issue of trail use has fueled years of acidic conflict among hikers, bikers, equestrians and dog owners, with the county sometimes resorting to barbed wire to block cyclists from trails.

“We do not condone this behavior,” Burnham said. “We advocate for legal trails. In Marin County, the trail user community is so polarized that anything that occurs is a blight that gets thrown on the community of mountain bikers.”

More was once a prominent bicycling activist, serving on the Marin County Open Space District Trails Committee. But he resigned the position in 2001 when federal authorities accused him and two other men of carving a four-mile illegal bike trail into the Golden Gate National Recreation Area near Bolinas Ridge.

All three men were indicted by a federal grand jury and eventually pleaded guilty to misdemeanors. They were ordered to pay more than $34,000 in restitution for the destruction to federal property, placed on probation for three years and banned from the federal park system during probation.

They apologized in court.
