Indian Rock (South Bay) Adopt-A-Crag: Coming Up May 20, 2017!

Join the Bay Area Climbers Coalition in partnership with Sanborn/Santa Clara County Parks department to take on some needed cleaning and maintenance around Indian Rock South Bay.  We will be cleaning up glass and trash, doing trail and rock stair maintenance, and removing graffiti.

Location:  Indian Rock is located in Saratoga.  A full description and detailed directions can be found on its Mountain Project website.  It can be confusing to find when going there the first time, so be sure to check a map before you head out.  Please note that Skyline is currently closed south of Indian Rock and Castle Rock.

We have found the easiest way to get to Indian Rock is the following:

  1. From CA-85, exit Saratoga Ave and head west
  2. Continue on Saratoga Ave; it will become CA State Route 9
  3. Follow CA State Route 9 up the mountain. The first stop sign you get to is CA-35; turn left.
  4. Follow CA-35 for about 2.5 miles.  You will see Castle Rock State Park on your right; go about 100 feet further, and you will see Indian Rock on your left.

Date:  May 20, 2017
Time:  10:00 A.M. – 1:00 P.M.
How To Join:  Sign up on Eventbrite!


Food – Delicious lunch will be provided as well as snacks to keep you fueled for the day!

Water – We will have water available. If you have a water bottle, please feel free to bring it with you.

Tools – We will provide tools and gloves–please be sure to wear long pants and close-toed shoes.

Climbing – The plan is to end the event around 1 pm to allow enough time for everyone to go climbing together!  Indian Rock is one of the premier Bay Area crags with amazing bouldering, top rope, and sport climbs. Many climbers know it as home to some of the best boulder problems in the greater Castle Rock/Sanborn County area. Feel free to bring your own gear for some post-event crushing at Castle Rock State Park, Indian Rock, or another of the many crags in the area.

We greatly appreciate the support from Planet Granite-Sunnyvale and Access Fund for this Adopt-A-Crag!

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.

Indian/Mortar Rock – East Bay – Adopt-A-Crag – March 2017

The Bay Area Climbers Coalition would like to thank all the incredible volunteers, board members, and friends who came out to support our conservation work at Indian Rock/Mortar Rock in the Berkeley Hills on Sunday, March 26. We were excited to partner with the awesome City of Berkeley Parks and Recreation department in this community effort!  We would also like to thank Access Fund for supporting this event with a grant!

With a 50% chance of rain forecast, we saw a solid turnout of 16 volunteers. The weather turned in our favor: cool and dry – perfect for getting out the shovels, wheelbarrows, and pitchforks!
We accomplished quite a bit during this event, including the following:
– We spread 4 truckloads of woodchips in the Pit and main use areas at Indian Rock.
– We removed heaps of downed tree branches from the Pit.
– We cleaned the runoff from the wet winter and resurrected the lower brim of the path near the Pit to prevent future impact on the path.
– We cleaned and rejuvenated paths around Mortar Rock and Indian Rock.
– We had a ton of fun!
All photos are thanks to Paulina @
The event is the first of many to come over the coming months (we just confirmed Glen Canyon in SF on May 13)! Keep an eye out for updates and upcoming opportunities to be involved soon.

Castle Rock State Park Adopt-A-Crag – April 2016

Our first ever Adopt-A-Crag at Castle Rock State Park was a huge success with over 40 volunteers that showed up to take on a number of stewardship projects throughout the park.  We are so excited to be working with the amazing staff that oversees Castle Rock State Park to build programming to better engage the climbing community around stewardship at Castle Rock.

This event is the first of many to come and we hope that you will join us for future events at Castle Rock and other crags throughout the Bay Area.

Our organization’s goal, as always, is to ensure long-term access to our local climbing areas through the building of relationships with land managers, educating the climbing community, and by hosting stewardship events to care for the areas we recreate.

What work did the 40+ volunteers complete during this event?

  • We repaired and rebuilt four split rail fences throughout the park
  • We installed four new sign posts throughout the park
  • We removed over 50 pounds of glass and trash from the greater Goat Rock area
  • We removed graffiti from a number of caves around the Goat Rock area
  • We also closed two social trails that were causing erosion to hillsides

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.
