Gary Prost above recycling center (4) small

Geologist Gary Prost’s talk went from the planetary to the hyper local, as he discussed what can be learned from the exposed rock face above the recycling center, a former quarry.

Geologist Gary Prost’s talk went from the planetary to the hyper local, as he discussed what can be learned from the exposed rock face above the recycling center, a former quarry.

Geologist Gary Prost led more than 30 hikers on an informative and at times exciting Hillside Natural Area Geology Walk earlier this month. If you missed it be assured – we will have Gary lead this hike again.

The hike attracted adults and families, and even though Gary handed out a reading list as part of his walk, the event was far from academic in tone. Kids on the hike loved getting up close and personal with the rocks as Gary explained their composition and how they were created.

Watch our website and newsletter for more. We hope to put this hike on again in the fall or early winter.

In addition, Gary, a retired professional geologist, prepared a useful handout, undoubtedly the best, short guide to the geology of El Cerrito we have ever seen. You can find it on our website.

The three-hour hike began at the Schmidt Lane trailhead to the Hillside Natural Area, wended its way through Madera Open Space, visited the nearby EBMUD water tank, went past the Berkeley Country Club’s golf course, and headed down the Great Western Power Trail along Moeser Lane.

During its course we learned about plate tectonics and how the movement of these plates created the California – and the El Cerrito – we know today. We learned to differentiate blue schist from rhyolite, two of the most common rocks found on our hillsides.

One is formed by the movement of the tectonic plates through subduction. The other is volcanic. We learned also about other rocks, including greywacke, about the work of thrust faults in making and remaking our landscape, and about strike slip faults.

Just as we did in our recent It’s Our Fault Hike led by another geologist, David Schwartz, we observed the Hayward fault as it can be seen along the golf course. Gary also showed us a spring that bubbles out of the ground along Regency Court, another sign of seismic activity.

I for one will never look at the El Cerrito Hills the same way again.

Trail Trekkers new hike leader Alina Constantiniescu put 20 people through their paces last night with a long (4 miles), beautiful and at times foggy hike that took us through the Hillside Natural Area, up the charming Shevlin to Arlington Trail, and through the Boy Scouts’ Camp Herms.

We thank the Boy Scouts for their kind permission!

Next we saw the quirky and fun Musee des Bibelots Voies on Leneve Place overlooking Wildcat Canyon, took a quick swing through a bit of Kensington past some beautiful mid-century modern homes, and took a small trail alongside the Unitarian Universalist Church.

Enjoying the Musee des Bibelots Voies.

Alina then led us down a hidden set of public stairs in El Cerrito that at first appear to be nothing but a driveway. Then down the Great Western Power Trail along Moeser Way as night fell upon us.

Alina will lead another Hillside Ramble, “mostly through the Hillside Area and Motorcycle Hill,” she says, on September 12, starting from the Schmidt Lane trail head at 6:30 p.m. Hope to see you there!

Until now, the bottom of the Motorcycle Hill Trail ended at a low wall that required a bit of a hop to get to level ground.

A major step – or rather, a series of steps – towards giving El Cerrito the usable trail system it deserves is finally happening. Crews have installed the steps at the bottom of Motorcycle Hill Trail.

We want to thank the El Cerrito Engineers, Ana Bernardes and Yvetteh Ortiz, and the Public Works Department for planning, overseeing, and expediting the construction of these inviting steps. We also are most appreciative to Joe’s Concrete for doing the installation. In addition, Trekkers thanks Glenn Wood, an El Cerrito resident and associate principal with the firm, SGPA Architecture and Planning, for providing the initial design, pro bono. Funds from Measure WW were used for this project; many thanks to the Park and Recreation Commission and the residents of El Cerrito for this community amenity.

Our vice president Jenny Hammer was the lead on building the trail. Trail Trekkers began work on the Motorcycle Hill Trail back in 2012 after identifying the site as public property and a good access to the northern Hillside Natural Area. We began with trail survey work overseen by Harry Silcocks of East Bay Trail Dogs, (another trail building group) and Charlie Bowen and others from Berkeley Path Wanderers. Their expertise and inspiration were invaluable. In addition, many volunteers participated in the trail building project, including Tom Gehling, David Lingren, Tim Aaronson, the El Cerrito High School Mountain Biking Team, and others too numerous to name. After we determined the route based on input from our experts, volunteers removed broom and poison oak, leveled the trail, and installed treads. Trail work is not complete; we still have more treads to install and some more grading to do.

The first Trekker hike on the trail was January 2013. There have been others, since, and there will be more in the future. The trail is used on a daily basis by runners, dog walkers, Madera Elementary School students, nature lovers, explorers. We encourage all to use the trail. We also send an invitation to all who are interested to join us for future work parties.

Jenny Hammer led a wonderful Trail Trekker hike, “It’s Our Fault,” this past Saturday, that explored the Hayward Fault as it makes its way through the El Cerrito Hills and East Richmond Heights.

This hiker is straddling a section of pavement on Olive Street in East Richmond Heights that has shifted due to the movement of the Hayward Fault.

Over fifty hikers attended this El Cerrito centennial hike and benefited from the expertise of Dr. David P. Schwartz, a Seismic Geologist from the U.S. Geological Survey, who has done much research on the fault and on earthquake and seismic issues. The hike was also useful in providing information about what we can do to prepare for the inevitable quake as the CERT Area 2 Coordinator Marlene Keller, was on hand to answer questions and distribute information about disaster/earthquake safety.

What was great about the hike was how it made the experience of  the Hayward Fault seem very real. You could actually see the fault, on the Berkeley Country Club (formerly Mira Vista) golf course, and crossing actual streets in East Richmond Heights.

You could see where sections of curb have been cracked and shifted (or offset) over the years by the gradual slippage of land along the fault. You could even straddle these sections, which many hikers did.

At one point, as we were talking about and looking at several homes that sit directly above the fault, the owner of one home nearby joined the discussion.

And then, in a special, unexpected treat of the sort that often occurs on Trekker hikes, we were warmly welcomed into and visited the beautiful Gyuto Foundation Tibetan Buddhist monastery, where we not only admired the Tibetan art and gardens — but were able to see how the reinforced concrete building has been pulled apart by the tectonic forces associated with our very own Hayward Fault.

Jenny had arranged the visit in advance, of course!

One bit of good news about this hike is, we plan to repeat it and will add more and different aspects. We’re not sure of the date for “It’s Our Fault: Redux” but you can keep apprised of this and our other upcoming hikes by signing on to our email list or by joining El Cerrito Trail Trekkers. Both can be done from our website, ectrailtrekkers.org).

I’m gratified to note that when the SFGATE website (that’s the San Francisco Chronicle) explained yesterday how El Cerrito got its name, the image they chose to represent the essence of our town was none other than the Hillside Natural Area! It’s wonderful

Patchie visited Madera Open Space with Trekkers and city officials before the area was purchased by the city

that the city is becoming associated in the wider public’s mind with this wilderness area, which Trail Trekkers will celebrate on May 21 during our fourth annual Hillside Festival.

Do not miss this event! We are putting together a great schedule now with hikes, talks, games and more for all ages.

Oh yeah, another reason I like the SFGATE photo — it shows my late and still beloved dog, Patchie, who served for years as Trail Trekkers’ mascot!

We want to re-focus our attention on trail building, including by installing steps at the bottom of Motorcycle Hill Trail. We also hope to finish construction of the Terrace Cutoff Trail and perhaps work on other trails as well.
We will continue the fight to preserve Fairview Open Space, the 15-acre wild land just north of the Hillside Natural Area, including building coalitions with other groups interested in open space, wildlife, creeks, air quality, parks and other environmental and community issues.
Trekkers will put on at least seven programs, including hikes and work parties that focus on El Cerrito history as part of the 2017 City Centennial.
The fourth annual Hillside Festival will be back and even better on Sunday, May 21.
We plan to create a printed version of our trail map this year for easy use by hikers, walkers and bikers.
We will continue to work with the city and Friends of Dorothy Rosenberg Memorial Park on planning for improvements in this new nature and garden park in the city’s hills.
We will work with PG&E to control overgrowth on the open space PG&E property, which is in between Moeser Lane and the Hillside Natural Area, while preserving and improving wildlife and natural habitat. We will work to ensure continued public access to trails on this property.
We will mount a membership drive to ensure that people in our community get involved with our organization and help support its mission through their participation, membership dues – and in other ways too.

During 2016, El Cerrito Trail Trekkers made great strides towards improving the trail and urban pathway network in El Cerrito.

We won approval for a plan to install trail signs throughout the city, both in the Hillside Natural Area and along urban stairways and other paths. This was a multi-year effort done in conjunction with the National Park Service through their Rivers, Trails, & Conservation Assistance Program. The city will fund sign installation in 2017 using Measure WW bond funds, thanks to unanimous approval from the Parks and Recreation Commission. We thank Patrick Johnston of the National Park Service for the imaginative signage design. It will make navigating the city’s many miles of paths much easier.
Also thanks to the National Park Service program, we have completed a map of all the city’s trails and pathways and will publish it in 2017. We thank Stephen Bowes of the National Park Service for major assistance developing and designing the map. This will be the first ever publically available map to the trails of El Cerrito. It will be free to members of Trail Trekkers and will be available to others for a small fee.
We are helping organize opposition to a proposed tract of mini-mansions on Fairview Open Space. In an effort to preserve 15 acres of wild land just to the north of the Hillside Natural Area, Trekkers met with a revived group named ECHO (El Cerrito Hillside Organization) to strategize fighting a plan to build 38 homes there. As we did two years ago with the Madera Open Space, we hope to add this land instead to the city’s Hillside Natural Area. The city has rejected initial proposals from the developer for several failures, including failing to explain how the plan would protect two creeks on the property, which combines grassland and forest and has a beautiful gorge with a series of cascades. The proposal will likely return in altered form for city consideration.
The third annual Hillside Festival was a great success, attracting about 300 people, including many families. We thank the city’s Environmental Quality Committee and Parks and Recreation Commission for co-sponsoring. We also thank the many organizations and individuals who led hikes, discussions, or otherwise took part, including the California Native Plant Society, Ranger Daniel Sanchez of the National Park Service, historian Richard Schwartz, the Golden Gate Audubon, the Northern California Geological Society, and others. We even had an outdoor meditation by Nicole Becker of Ojas Yoga Center. The festival raised funds for hillside maintenance.
We worked with other groups in the city on plans to open the Dorothy Rosenberg Memorial Park. The park may include a native plant nursery, environmental education and a meeting place for local non-profit groups. There will also be an alternative entrance via a short trail
Girl Scout Troop 31352, with the encouragement of Trail Trekkers, has renewed and restored plantings the troop installed two years ago at the Tassajara Steps near Tassajara Park. Robin Mitchell of the Community Garden Network was instrumental in helping the Scouts select native plants for the initial installation. We thank the Girl Scouts for their dedication to community improvement along our trails.
Trail Trekkers led more than two dozen hikes during the year, ranging from tours of the natural landscape on Albany Hill, to a hike past the city’s small but beautiful waterfalls, to an architectural tour of storybook-style homes, to a hidden geo-caching poetry hike. Our hikes are free to all.
At our annual meeting in 2016, the group of Raptors are the Solutions (RATS delivered a valuable presentation about protecting birds of prey from poisons used to control pests.
Trekkers held its first ever Members Appreciation Party this holiday season. It proved so successful we will do it again next year, and may add a spring appreciation party too.
Trekkers added to its board of directors a new member, Mollie Hazen, a longtime active member of the El Cerrito community. An event producer, legislative health care advocate and photographer, she operates Hazen Nature Photography, exhibiting photos of her late husband Don R. Hazen. She also serves as board president of the Kensington Symphony Orchestra and as an El Cerrito Arts & Culture Commissioner. Mollie is a longtime member of the El Cerrito Crime Prevention Committee, received legislative recognition for her outstanding work in uniting the community against crime.
