Glen Park Adopt-A-Crag: Coming Up May 13, 2017!

Join the Bay Area Climbers Coalition to take on some work in beautiful Glen Canyon, nestled in the heart of San Francisco’s world-famous hills! Activities will include cleaning up glass and trash, clearing paths and walkways, trail repair, and graffiti removal.

Location: Glen Canyon Park is located in the Glen Park neighborhood of San Francisco, a pleasant 10 minutes walk on flat ground from the Glen Park BART station. provides a great overview and directions. The park is a popular spot on weekends, so parking can be challenging; carpooling or public transit is recommended if at all possible. We’ll be meeting in the middle of the park, at the northern end of the dirt road that runs alongside Islais Creek, just across from the Silvertree camp / Glen Ridge pre-school building.
Date: May 13, 2017
Time: 10:00 AM to 2:00 PM
How to Join: Sign up on Eventbrite!


Safety – We are HUGE on safety! There will be a safety talk at 10am on the day of the event. Please note that we require all participants to be present for the safety talk and wear closed toe shoes. Unfortunately, we cannot allow anyone to participate that does not wear closed toe shoes and/or attend the safety talk.

Food – Lunch will be provided for all volunteers.

Water – Drinking fountains are available a 5 minute walk down at the bottom end of the canyon (near the Rec Centre), but to save time, please bring a water bottle.

Tools – Tools and gloves will be provided by the San Francisco Recreation & Parks Dept, but feel free to bring your own work gloves if you prefer.

Bathrooms – A porta-potty will be provided by the San Francisco Recreation & Parks Dept near the project areas.  There are also bathrooms down at the Rec Centre; however, since it is currently under renovation, the bathrooms may not be open.

Clothing – Sturdy, closed toe shoes are mandatory.  The canyon can be foggy and windy in the summer months; a windproof jacket is recommended.

We greatly appreciate the support from Access Fund for this Adopt-A-Crag!

Did You Know…
The first dynamite factory in the United States (est. 1868) was based in Glen Canyon (then sparsely populated) right around the current location of the Rec Center.  It exploded in 1869, killing 2 workmen and leveling the facility. It was rebuilt out in what is now the Sunset District (that facility also exploded).

Some older folks remember rafting on Islais Creek (the creek in the bottom of the canyon) during winter and spring.  Apparently, changes in the size and drainage on O’Shaughnessy Blvd and Portola Avenue, as well as the build-out of Miraloma Park (1930s-1950s) and Diamond Heights (1960s) substantially reduced the amount of surface runoff reaching the creek, reducing it to the small (though pleasant!) trickle it is today.

The rock is radiolarian chert – a sedimentary rock composed from the compressed silica-rich casings of dead single-celled marine organisms.  While not rare worldwide, it rarely outcrops in a way that is good for climbing. Apart from a few outcrops further up the Marin and Sonoma coasts, there is very little other chert climbing in the world.

Mount Tamalpais Adopt-A-Crag 2016 Event Report

Last February, we partnered with One Tam to host a Mount Tamalpais Adopt-A-Crag event, and it was a total success! Under sunny skies, over 30 volunteers showed up to clean up glass and trash, close social trails, and improve the hiking trails that lead to some great climbing areas. The volunteers showed up early and got a ton of work done!

Huge “thanks” to Touchstone Climbing and Planet Granite for hooking up the raffle prizes for the event. We also want to thank High Tech Burrito for providing a great non-profit discount on a pile of tasty burritos to feed all of our hardworking volunteers. And another thank you shout out to our volunteer team leaders and to Francois Lebeau for taking photos of the gorgeous scenery, all of our awesome volunteers, and documenting all that hard work.

Here is a quick list of the work that we got done at these amazing local climbing spots.

East Peak:

– picked up over 50 pounds of glass and trash

– cleared overgrown branches from 300 feet of trails around the climbing area

– closed 5 social trails

– cleared rubble and loose rocks from over 4000 feet of trail

– cleared debris out of 16 water bars to allow water to easily shed off the trails

– removed 16 dead tree stumps from the trail

Lakeview Boulders:

– built 2 check steps where erosion was occurring on the approach trail

– cleared the approach of debris and leaves

– cleared overgrown branches from 150 feet of trails around the climbing area


Thank you again to everyone that came out to put some love into our local crags!



























Indian + Mortar Rock Adopt-A-Crag 2015 Event Report

Two of our amazing board members – Ally and Caden – got the chance to run their very first Adopt-A-Crag event at Indian and Mortar Rock and it was a huge success. Over 30 volunteers showed up to take on some needed work at Indian and Mortar Rock last Sunday. These volunteers worked crazy hard and got a huge amount of work done in a very short time!

Huge “thanks” to Planet Granite, Touchstone Climbing, and CLIF Bar for hooking up the raffle prizes for the event.  We also want to thank Rotten City Pizza for donating a number of their tasty pies to feed the hardworking volunteers.

Here is a quick list of the work that we got done at these amazing local climbing spots.

Indian Rock:
– picked up tons of glass and trash – easily 60 pounds
– installed new wood chips in The Pit, up top near The Ape, and along the start of the Indian Rock Traverse – 10 cubic yards in total!
– cleared dirt and pulled weeds from the main stairs leading down to The Pit
– swept all the pathways around the park – the neighbors love this

Mortar Rock:
– picked up trash from around the park
– cleared the stairs around the back side of debris and leaves
– installed some new rocks along the pathways to better define and discourage cutting through the planted areas

Thank you again to everyone that came out to put some love into our local crags!



2015 Fall Highball – Sads Trail Work

The American Alpine Club hosts a number of Craggin’ Classic events across the country. These events focus on bringing the climbing community together and they always build in a stewardship project – all things we are totally in love with!

The Fall Highball in Bishop is a great event and excuse to get some Eastern Sierras crushing in while also making some time to help out with stewardship projects at the Buttermilks, The Happys, and The Sads. These climbing areas are very popular and get a lot of traffic during a very short season so the more that the climbing community can do to support and maintain these areas, the better.

Three of our board members – Allyson, Caden, and Matt – all made it out to this event and did some great work on the approach trail to The Sads.

The trail from the Chalk Bluff Road side of The Sads ascends a fairly steep hill and with all the traffic this trail sees it is in fairly good condition. Our team lead a smaller team of volunteers to make some improvements to this trail. With only 3 hours of work and 8 total volunteers, we were able to get a lot of work done.

Ally did some amazing work higher up on the trail where some of the existing stairs had come loose and were being washed out from heavy traffic. Stairs were fixed and cleared off to help better define the correct trail to use.

Caden and Matt added an extra stone stair about 1/4 of the way up – there was a big gap between the existing stairs and the outside edge of the trail was blowing out from folks walking on the outside edge. They also added some rocks on the edge of the trail to provide a visual marker for folks.

We also had some help from local crusher – PAULA!!!!!

There was also another area where folks were side-stepping the stone stairs. This side-stepping was causing the outside edge of the trail to blow out and knocking rocks down the hillside. To stop the erosion issues and keep folks on the correct part of the trail we added a rubble wall.  Here is the before photo:


Here is the after photo – note the wall on the left side of the trail and the better defined stairs.


Remillard Park – CLIF Bar Employee Volunteer Day

The Bay Area Climbers Coalition has been partnering with the amazing folks at CLIF Bar since we started this organization. Everyone that we have worked with at CLIF Bar has been super passionate about stewardship and volunteering within the community. So when they approached us about doing a larger volunteer work day for 50 employees we were over the moon excited to work with them.


A big part of being a true partner with land managers is to listen…odds are you will hear about challenges they are having that you might be able to help out with, even when they have nothing to do with improving the climbing areas of a park. Remillard Park in Berkeley has some great top-roping and boulder problems, but the major work that needed to be taken on at this park was not in the climbing areas directly.

The 50+ CLIF Bar employees that volunteered their morning with us helped to make some major improvements to Remillard Park, including:

– removing blackberry bushes from the ivy on the hillsides
– clearing out broken glass, trash, and green matter from the sand in the kiddy play area
– trimming the ivy back from the pathways around the kiddy play area
– clearing the pathways and stairs around the kiddy play area of weeds and other invasive plant species
– weeding and trimming of bushes from fencing and pathways around park
– clearing of green matter from trails around back of rock
– clearing of trash and broken glass from trails around back of rock
– fixing of cross-slope on trails around back of rock

HUGE “thank you” to all the CLIF Bar employees that came out to crush all of this work in under 3 hours!



















Fundraising Raffle – July 17 at Berkeley Ironworks


We partnered with Berkeley Ironworks earlier this month to host a huge fundraising raffle during their Touchstone Climbing Series bouldering competition.

We are extremely proud to say that the fundraiser was a huge success!

Our goal was to raise at least $2,000 to purchase the equipment needed to take on more rebolting projects at crags throughout the Bay Area. The replacement of aging bolts is a huge undertaking and having enough of the right tools to do it cleanly and efficiently makes a world of difference.

Because of the amazing support of Berkeley Ironworks and the incredible psyche from the climbing community, we raised $3,500 to support stewardship projects and rebolting efforts at local crags.

We specifically want to call out the folks at Ironworks – they are incredible and have some of the deepest love for our local climbing that we have seen. Not only did they provide us with the venue to host the raffle, they also sold raffle tickets all week before the event, and they donated all of the non-member $10 competition entrance fees to the Bay Area Climbers Coalition. Those entrance fees made up half of the $3,500 that was raised.

Thank you to everyone that purchased raffle tickets – your support will ensure safer bolts and better trails at crags throughout the Bay Area.

And HUGE “thank you” to all of the companies that donated products – without them this would not have been possible.














Glen Canyon – San Francisco – Adopt-A-Crag – 6/6/2015

The Glen Canyon Adopt-A-Crag was a great event and we want to give a very special “thank you” to the 36 local climbers that came out to make this event a success.

Recent History:

As many of your know, there were some concerns from the SF Parks and Recreation department about climbing in Glen Canyon Park and at Beaver Street Wall. A number of us from the local climbing community (Teresa Black, James Craig, and Matt Ulery) met with the SF Parks and Recreation department employees to understand their concerns and identify how to move forward to ensure continued access to these great local gems.

One of the opportunities that was identified was the hosting of an Adopt-A-Crag at Glen Canyon. This event was our opportunity to show the local land managers that the climbing community in the Bay Area are passionate and dedicated stewards of their outdoor spaces. And thanks to all of the volunteers that showed up and worked super hard, we were successful in that area.

The Bay Area Climbers Coalition will continue to work with the SF Parks and Recreation department to establish a more formal “climbing management plan” that will include ongoing stewardship events and educational components to keep you all in the loop about what is going on in the parks and how we can be the best possible partners.


Event Report:

With all of our Adopt-A-Crags we love to celebrate the work that was completed at a local crag, check out the summary and photos below!

Work completed included:

  • Clearing of brush from trails around park – these trimmings were used to close off a major social trail to the climbing area that was causing erosion issues. Please be sure to stay on the established trails in Glen Canyon (and other spots too).
  • Filling and crowing of dirk pack in crib/box steps that lead up to the main climbing areas – when the steps were originally built the treads were not packed correctly, with the guidance of the SF Parks department we fixed this issue on over 30 stairs leading up to the climbing area.
  • Trail restoration and erosion control – two teams took on some serious trail restoration and erosion control on the trails around the climbing areas. Work included widening of the trails, bench-cutting, and correction of trail cross-slope. All of this work will make the trails easier to use and allow for better shedding of water off the trails and reducing erosion.
  • Removal of fencing and fence posts around climbing area – the SF Parks department had put up this fencing on the hillside around the climbing area to provide the hillside the chance to regrow a number of native plants – with the regrowth completed, the fence could be removed.

One of the things that we LOVE about these events is that we provide an opportunity for climbers to learn about all the technical details that go into the restoration and maintenance of the trails and systems that make up the areas we recreate. So even if you have never done this type of work before we will work with you to understand the importance of the work you are doing and develop some hard skills that you can bring to the next event with us.


Huge “Thank You” to our partners and Sponsors:

These events would truly not be possible without the support of these amazing local businesses. The Bay Area Climbers Coalition is a volunteer-run 501c3 non-profit and we rely heavily on the generosity of local business to keep the costs of these events to a minimum. Please be sure to check these business out and support them as a way of saying “thank you” for their support of us and our local crags.

Dry Sea Crag – Rebolting Project

Bolts – there is a lot of unknown trust that goes into clipping that bolt and having faith that it will hold a fall.

There is a lot that goes into the integrity of a bolt…..who placed it, what kind of bolt did they use, is the rock solid enough, how old is the bolt, what kind of environmental factors have come into play, is it rusted where I can’t see?

Bolt technology and bolting standards have come a long way over the last twenty years. Luckily in the Bay Area, we have a number of veteran bolters who have invested a lot of time and money into ensuring that our local crags stay safe. Jim Thornburg is definitely one of those people.

When Jim Thornburg approached us about working with him to tackle the replacement of some obviously rusted and dangerous bolts at Dry Sea Crag, we were 100% up for it. As you can see from the photo above, the old bolt on the left was definitely in need of replacement. The new bolt on the right, a glue-in titanium, has been a popular option for ocean-side crags around the world.

The all-star team of experienced bolters – Jim Thornburg (author of Bay Area Rock guide-book), Casey Zak (BACC Vice President), and Steven Roth (amazing climber and experienced bolter) – were able to install 26 new bolts and remove 6 old bolts.

Why didn’t they remove more of the old bolts? Unfortunately, a lot of the older bolts were so far gone that they were not possible to get out without risking damage to the rock… when you are climbing at Dry Sea Crag and you see two bolts, pick the one that isn’t rusty.

The Bay Area Climbers Coalition has established a Bolting Advisory Group to work with land managers and experienced bolters like Jim Thornburg to take on projects like this at crags around the Bay Area. If you have experience with bolting and are interested in helping out, please drop us a line –

Huge “THANK YOU” to the ASCA (American Safe Climbing Association) for providing the drill bits, glue, and titanium bolts!

The Berkeley Triple Adopt-A-Crag – November 2014

The first annual Berkeley Triple was a huge success thanks to the 92 volunteers who took on some needed work at Indian Rock, Mortar Rock, and Cragmont Park.

This event went a very long way in building an even more positive relationship with the City of Berkeley Parks Department. When the climbing community shows up in force like this to support our outdoor climbing areas, it shows land managers that we care and opens up opportunities for future improvements to our crags.

HUGE “Thank You” to our sponsors and partners – these events are operated at zero dollar cost because of their generous support and donations.

Make sure to swing by the Bay Area Climbers Coalition facebook group for more photos!

Highlights Include:

Indian Rock – Removed ivy and other invasive plants from the back wall area next to Picnic Rock. Raked leaves and other debris up around the park and cleared all of the trails off. Picked up three large bags of trash and glass from around the parks.

Mortar Rock – Closed 4 social trails around the park and more clearly defined a common use trail to avoid future social trails. Cleared all existing trails of leaves and debris. Cleared stairs and sidewalk leading up to Mortar Rock. Removed old trash can pole.

Cragmont Park – Cleared ivy and other invasive plant species from rock walls and surrounding hillsides. Trimmed tree branches that were growing too close to the rock face. Recut existing trail and installed check steps at different spots to decrease erosion and provide easier use for patrons. Removed old and rotted timber from back trail that connects climbing areas back up to the basketball court area – used large broken cement pieces to rebuild retaining wall and create steps for much safer use.

Thank you to our sponsors and partners!
