A short rocky section of trail.

When I became the Maintenance Chair for the Sonoma Overlook Trail Stewards, I stepped into a role of responsibility that I never thought I would take. But it has been surprisingly interesting and rewarding. I’ve learned a lot along the way, particularly by also volunteering with the trail maintenance team at Sugarloaf Ridge State Park. Along the way I’ve invented some things. One of them I dubbed “Rock Patrol,” introduced in a previous post.

Since then, I’ve realized that there are two different activities, not one—rock patrol, which is a solitary task of removing individual problem rocks from the center of the trail and infilling with soil, and tread renewal, which is a more systematic effort of rock removal from a section of trail and a renewal of the tread with gravel and/or soil. You more often do tread renewal with a team, but not necessarily.

Today I went out and blurred the lines between the two, as well as pioneering another technique, that I’m calling rock reduction. There are some rocks in the trail that can’t be removed, as they sink too deep into the trail or are bedrock. However, I’ve found that many rocks on the trail can be “reduced” by striking them with a steel prybar and chipping pieces off the top and/or fracturing parts off the side. By using both of these techniques it’s possible to reduce the level of the rock below the trail, and then covering it over with soil. The picture shows the rock at the bottom of the first picture that has been “reduced” to the point where it can be covered.

The point is to create a smooth tread that fails to trip hikers, and especially runners, as they traverse the trail. As someone who has fallen badly a few times when trail running, I understand the importance of removing (or reducing) trip rocks.

We understand that this work can only progress at a snails pace, as each section of trail requires a good deal of effort. But progress it will, and like our efforts to reduce and control invasive species this is a long game. And we know exactly what a long game requires.

Today’s project had a further nuance. If you look at the first picture, at the rock at the top left of the trail, compare it with the bottom picture. We successfully reduced it’s width by breaking the side of the rock impinging on the trail, therefore widening the clear path. Nuance like that can easily be overlooked, but it matters, as it produced a wider smooth trail. Eventually, every inch of trail will have had this kind of attention.

Every month on the first Monday, the Sonoma Overlook Trail (SOT) Maintenance Team has a standing workday. Sometimes we do “rock patrol” where we remove rocks sticking up in the trail and fill in the holes, sometimes we pull invasive thistle and cut back poison oak, and other times we engage in more traditional trail maintenance activities, like we did today.

Today a team of four stewards on the Maintenance Team worked to shore up a section of trail that was in danger of falling away, and spread gravel to create an outslope that encourages “sheet flow” of water directly off the trail when it rains. This project was assisted by the remnants of rock and gravel left behind by the American Conservation Experience (ACE) crew who recently worked on three sections of trail to make them easier to traverse and more sustainable.

After the ACE work had been completed, volunteer stewards Bill Wilson, Fred Allebach (both of whom were instrumental in getting the ACE work completed) and I walked the renovated sections of trail and identified the portion of trail we worked on today as needing work. With four of us working, and the materials we needed close at hand, it only took us an hour and a half to complete the job.

Yesterday the partial trail closure on the Sonoma Overlook Trail was removed, as the work that we had contracted with American Conservation Experience (ACE) to accomplish was completed. They ably reworked three sections of trail that have been problematic. These stretches were rocky, hard to traverse, and presented drainage issues.

Volunteer Bill Wilson competently and thoroughly planned the work, coordinated with ACE and the City of Sonoma (also a participant in this work), and managed it in association with the ACE Team Leader. Volunteer Fred Allebach was the on-site supervisor for the SOT Stewards and the City, and also helped out crushing rock and other trail construction tasks.

We hope you enjoy the improved sections on your next hike!
