With thisnearlycompletechange in the team responsible for Bay Nature (except — for better or worse — yours truly) there are bound to be changes coming in the magazine itself. What they’ll be, I don’t yet know. But I’d love to have your input as we figure it out, so I invite you to participate in the Bay NatureReaders’Survey(baynature.org/ survey). It will only take ten minutes of your time, but it will definitely help us chart our future course. One possible direction: more of the cross-platformcoverageofsubstantive issueswe’veinitiatedwiththe“Fracking intheGoldenState”seriesthathasbeen rollingoutonBaynature.orgsinceearly August (baynature.org/fracking) and continuesinthisissue.Bylookingatthe underlying geology and the potential habitatimpacts,wetakeauniquely“Bay Nature”approach to this controversial topic and hopefully help inform your personal take on it.

In front of her, the normally sandybeachwassubmerged.Theaccess roadtothebeach,whichrunsparallelto the freeway, was also under a couple of inches of litter-laced water. The flooding was not the result of a biblical deluge or a freak winter storm pushed by crisp winter winds from the North Pacific. Instead, the Bay nearly lapping the toll plaza was caused by a particular alignment of the sun, the moon, and Earth, causing an extreme tidal event. Big tides happen when the moon’sellipticalorbitbringsitclosestto the earth while it is also in a full or new phase.Suchgravitationallyinfluenced extreme tides usually happen twice a year. They are called perigean spring tides, or, more colloquially, king tides. Drinkwater,aBerkeley-basedarchitect who is also a board member of the grassroots nonprofit Friends of Five

From scenic Point Arena Cove to Irish Beach, almost 11 miles to the north, all of this coast is now public land, including the just-acquired 409 acresknownasCypressAbbeyPhase2,

It’snosurprisethatthemonumentis abitobscure:It’stheonlynationalmonumentthat’stotallyoffshore,composed of islands and rocks along California’s 1,100-mile coastline, from Oregon to Mexico.SenatorBarbaraBoxerandRepresentativesMikeThompsonandJared Huffman have proposed legislation to make the public coast around Point Arena the only onshore portion of this little-known national monument. If Congress fails to act, President Obama could make the designation himself. “Most of these bluffs are already public land,” says Ryan Henson of the California Wilderness Coalition, “yet they lack the protection of places like the Golden Gate National Recreation Area, Redwood National Park, or the King’s Range Wilderness.” Buttheydeserveasmuchprotection as they can get. As we started the tour, a short walk took us to the bluff behind city hall, highabovethecove,deliveringonHodder’s promise of stunning views of the coast, the pier, and some fishing boats bobbing in the swell. This slice of bluff is Cypress Abbey Phase 1, 123 acres ownedbytheBureauofLandManagement since January 2012.

Continuing north, we came to a gate with a“no trespassing” sign:thejust-acquired409acres ofundevelopedcoastalbluffsand critical habitat of Phase 2, with over a mile of coastline, which forms a central link connecting more than 3,300 acres of permanently protected open space north and south of this parcel.

But even the single terrace at Point Arena creates plenty of drama. It was eroded by waves at sea level about 100,000 years ago, says Bay Area geologist John Karachewski, and uplifted to its present elevation by continued and active mountain building along the California coast.“The sedimentary layers exhibit different hardness,” he explains, “which the waves exploit to erode the land into these scenic and beautiful headlands, coves, and sea caves.” When he visits, Williams likes to take his field trip participants back and forth across the San Andreas Fault as they travel from Fort Ross up to the town of Mendocino. On the west side, the rocks of the Gualala Block have movedapproximately300milesnorth along the San Andreas and are significantlydifferentfromFranciscanAssemblage rocks east of the fault.“It’s a fascinatingarea,especiallyrighttherearound Point Arena.

The current oil boom in California is being driven by new technologies that make it possible to extract oil trapped in shale layers (note the dark stains in the sample below) of the Monterey Formation, which runs under the arid hills and valleys of Central California (such as Mustang Ridge, above, south of the Pinnacles), home range for the endangered California condor (above left).

The Monterey Formation extends beneath much of California, underlying the Central Valley and emerging in outcrops in the Coast Range and along the coast. It consists of rock layers, often fractured by faulting, deposited between 13 and 6 million years ago in offshore marine basins. The fossils of microorganisms that lived in the sea are the source of the oil in the shale layers.

The open, arid country of central California targeted by oil companies and patrolled by California condors can appear almost lifeless in the heat of the day. But it harbors a large number of listed species, many of which take refuge underground, including (from left to right) burrowing owls, kangaroo rats, San Joaquin kit foxes, blunt-nosed leopard lizards, and antelope ground squirrels.

Legislative Action on Fracking Given the many serious concerns raised about the environmental impacts of fracking and the lack of state regulations to address the risks associated with this and other forms of “well stimulation” (including acidization and steam), State Senator Fran Pavley introduced SB 4 in early 2013. The bill strengthens permit requirements for all such “nontraditional” oil recovery methods, requires full disclosure of the chemicals used in the fracking process, and mandates studies of potential earthquake hazards and water quality/supply impacts. Some environmental groups supported the bill, while others were disappointed that it did not include a moratorium while studies were carried out. However, the bill that passed both the Senate and Assembly in midSeptember included last minute amendments pushed by the oil industry that most environmental groups claim will exempt fracking from environmental review. And so, as we go to press, these groups are urging Governor Jerry Brown not to sign the bill. To find out more go to cleanwateraction.org/fracking-california.

That, long before I even saw a Bunsen burner or the periodic table, is how I learned about pH. ThepH(“powerofhydrogen”)scalereflectstheconcentration of hydrogen ions in a solution. Distilled water has a“neutral” pH of seven. A lower-pH solution is acidic; higher, alkaline. Fourier’s lemonade is about 2 or 3.

JC:Whatweretheearlyinfluencesthatledyouto your current career? SG: I grew up in Mill Valley when it was really still quite wild. There was an intergenerationalpodofkidsandwe’d all play outside — being inside was boring. None of us considered staying insidebecauseitmeanthavingtohang out with our parents, where there was nothing to do. So, growing up with so muchopenspacesurroundingmereally helped to develop my connection to nature. Then when I was in high school we had to do 100 hours of community service.Igothookedupwithaprogram that was running a summer camp that was free to kids referred from local social service programs. Everybody who worked at the camp was a volunteer, from the director to the cook to the counselors. They did it to give localyouthcomingfromtryingcircumstancesanopportunitytohaveacamp experience. We did everything from archery to hiking to arts and crafts —  we were outside every day and that’s when the healing and connective power of nature became clear to me. That was a transformative experience for me. JC:Howdidyoustartgettingthecommunity involved in stewardship? SG: I first got started myself up at Point Reyes National Seashore. I was just out of grad school and I was hired onto a projecttoremoveFrenchbroomfroma wildernessarea.Itwassupposedtotake six to eight months, but I was able to do it in two or three months because I started working with the Boy Scout troops and volunteers. It seemed like a bay nature

win-win: Not only did the work get done twice as fast, but we fired up a group of volunteers that could help maintain these areas over time. That’s how I became more aware of the value of engaging the community. When I started working here in the Golden Gate National Recreation Area there was already a small group of indi-

Wehaveanotherteamthatworkson connectingvolunteerstotrailandrestorationprojectsineachofthethreecounties the park is in: Marin, San Francisco, and San Mateo. And then we have a whole separate team that runs youth programs. They canspinoffanddoprogramsseparately, or connect up with all the other volunteer programs in the park, or link up


with our park partners. So for instance, this week the youth in our summer programsworkedinthehistoricgardens on Alcatraz, kayaked on Lake Merced, removedgraffitifromhistoricstructures in the Marin Headlands, and pulled French broom in Oakwood Valley. JC:Andwhat’syourroleinmakingallthis happen? SG: My role is to support a brilliant team of staff and interns who then engagethelocalcommunityinhabitat restoration,trailmaintenance,andyouth programming — it’s pretty big and diverse. You also asked me about my strengths. I would say I’m a decent volunteer manager, but my real skill is making connections. I get very excited about building partnerships and, through these new relationships, connecting more people into the park. I also think I’m really good at surroundingmyselfwithtalentedindividuals who bring different skill sets and perspectives —  soasacollectionwe have a broader array of talents thananyofusdoindividuallyand wecanapplythistotheprogramming we co-create. JC:Hasrunningthisprogramchanged the way you look at a landscape? SG: What I’m really awestruck by is the transformative nature of thelandscapeforthepeoplewho engageintheprograms.Ourfocus hasbeenonconnectingvolunteers to take care of the land. But what I’vecometorealizeistheinverse —  how being out in nature transformspeople,sometimeswithout their even realizing it. I’ve witnessedthisonsomanyoccasions, particularly with the youth programs. Many of the youth in our summerprogramscomefromSan Francisco and other urban local areas,andwestartbytakingthem to Yosemite for four or five days of camping. They often start out tentativeanduncomfortablebeing away from the lights, Wi-Fi, and thecreaturecomfortsofthecity.I

watch how there’s almost a dna-level transformationthatoccurswhenpeople are in nature: It resonates that deeply sometimes.Bytheendtheydon’twant to leave. What’s really neat for me is knowing it’s a two-way street: All the work we’re doing creates a positive impact for the resources,andthenaturalareasaregiving as much back to us, if not more. JC:Whataresomeofthechallengesyouface? SG:Ithink,foravolunteermanager,the biggestchallengeisnotburningout.A goodvolunteermanagerputshisorher wholeheartintothejob — everyvolunteer is basically a friend, and hosting a volunteerdayislikehavingpeopleover to your house a few times a week. If the manager is connecting with both herhead and heart it’s very exhausting over time. So one of the keys has been settinggoodboundaries,findingways to reenergize myself, and developing amazingpartnershipswithotherswho share the responsibility of caretaking the volunteers.

Pinned to Gardner’s wall for inspiration is a copy of this passage written by Diego Ochoa, a high school student who worked in her park stewardship program: When I heard Shelton Johnson, the Buffalo Soldier expert/park ranger, tell Eddie that “going back to the city wasn’t going back to the real world. This here is the real world; everything in the city was created,” I really began to feel that this was the answer I had been searching for. That this was the answer to my question, “What is it that I feel when I am out among the trees, birds, beautiful sites, or even when I breathe air that has not yet been polluted by heavy pollution?” I had found my answer. It was home. . . . [Parks] are our home. We can go there and not be judged or discriminated against. We can be ourselves. . . . As long as we can all grasp that feeling that reminds us that we are human, and nothing more special than a ponderosa pine or a black bear, we can live a more peaceful life in our home. And that is how my connection to nature came. I did not hear or see it. I felt it.

Mychallengeshaveshiftedovertime becauseI’mnotdoingasmuchone-ononevolunteermanagementanymore. Now I worry about how to maintain funding and support for the programs over time while supporting the staff andinterns.Itendtoseeopportunities aroundeverycorner,soIhavetobecarefulnottooverwhelmmyteamormyself. And I do make a point of getting out into the park once or twice a week so that I can connect with the staff on the ground and to make sure that I’m connected with the resource that I’m ultimatelyworkingtorestoreandconnect people to. JC:Whatisyourfavoritethingaboutthepark? SG: There are two things I really love. First, that our parkland is a public asset: it’s for everyone. That’s part of what we do in stewardship: introduce more people to the parks and invite them to return. I also love its location. Being so close to the city allows a lot of opportunities for people to get involved. I know of very few cities like San Francisco, whichhassuchanamazinggreenbelt surrounding it. We are so lucky. JustthisweekI’vebeenhelping outwithouryouthprogramsmore than I normally do, and I’ve been so struck with the diversity of habitatsandopportunitiesinthis park — the range of cultural and natural resources just blows me away. You can be out one day repairing an old ship used to haul timbers in the Gold Rush era and the next day you can be underground in a battery at Fort Cronkhite or out on Alcatraz helping restore the gardens, or hiking the trail at Dias Ridge above Muir Beach and helping to restore native habitat there. It’s just a crazy amount of diversity and richness. I hope I can inspire others to come check it out!  LearnmoreaboutGGNPC’sParkStewardshipprogramatbit.ly/ParkStewardship.

sand as usual, and so this summer the beachisuncommonlywide,leavingmore space for the plovers to coexist with people and their dogs. Yetfargreatersurpriseswereinstore for the scientists following the Stinson Beach saga. As Lynne Stenzel of Point
