One of them was, \"I've got oil wells in Bakersfield, pumping pumping pumping.\" We think of our petroleum as a Southern California thing, or at least no closer than the Great Valley. But petroleum—oil and gas, or both—is widespread around the state, including the Bay Area.\u003c/p>\n\u003cp>It wasn't just gold, water and agricultural soils that made California rich. Petroleum is one of our greatest natural assets, and the state still ranks fourth in oil production behind Louisiana, Texas and Alaska. While the forests of derricks that once dotted Los Angeles are now subdued and disguised, the Central Valley is still a proud petroleum region, with gas fields in the Sacramento Valley and oil fields in the San Joaquin Valley.\u003c/p>\n\u003cp>The oil and gas fields of the Central Valley intrude into the Bay Area from the Delta as far as Concord and the Suisun Bay to its north.

Photos by Andrew Alden.\u003c/sup>\u003c/em>\u003c/span>\u003c/p>\n\u003cp>San Francisco is \"America's Favorite City\" for many great reasons. Geologists have their own list of reasons to love it, many of which are Franciscan—by which we mean the peculiar association of rocks found up and down the Coast Ranges. Corona Heights is a small hill west of the Castro district that features some of these rocks, but one of its main attractions is a world-class slickenside.\u003c/p>\n\u003cp>\u003c!--more-->\u003c/p>\n\u003cp>You get to Corona Heights by walking about a mile west from the 16th/Mission BART station, or by taking the F line up Market Street to the Noe or Sanchez stops. Here's the hill as seen from 16th Street. You can't miss it.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/07/corona1.jpg\" alt=\"corona heights\">\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>Corona Heights is a hardworking hill that formerly yielded clay and chert. Years of quarrying have accentuated its rugged appearance and left splendid exposures of the bedrock. Along the way, if you keep an eye on appearances of old concrete (doesn't everybody?), you may spot the old chert aggregate around the neighborhood.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/07/corona2.jpg\" alt=\"chert aggregate\">\u003c/p>\n\u003cp>Corona Heights, like Bernal Heights to the southeast, is an island of resistant chert that is part of the dismembered \u003ca href=\"http://www.kqed.org/quest/blog/2011/04/21/geological-outings-around-the-bay-marin-headlands/\">Marin Headlands terrane\u003c/a>.

It has a \u003ca href=\"http://sfnaturalareas.org/pages/1\">dedicated group doing habitat restoration\u003c/a>. But we're here to see the slickenside.\u003c/p>\n\u003cp>A slickenside is the polished surface that is created along a fault as the rocks rub against each other. They are common in faulted rocks, but only in patches the size of your hand. (I showed you some in \u003ca href=\"http://www.kqed.org/quest/blog/2011/04/14/calera-limestone-a-gift-from-the-ancient-pacific/\">the Calera Limestone\u003c/a>.) Larger ones are rarer. Quarrying at Corona Heights uncovered one the size of a big front yard, one of the world's largest exposures. To see it, start at Castro and 15th, go uphill on 15th and turn left on Beaver Street. Again, you can't miss it.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/07/corona3.jpg\" alt=\"slickenside\">\u003c/p>\n\u003cp>The site is also a playground, named for Sidney Peixotto. If you continue up 15th Street instead, you'll see the exposure this way.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/07/corona4.jpg\" alt=\"playground and slickenside\">\u003c/p>\n\u003cp>But the real joy of the thing comes at close hand, where you can feel the mirror-smooth surface that only a hard stone like chert can provide.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/07/corona5.jpg\" alt=\"fault polish\">\u003c/p>\n\u003cp>Surfaces like this are of scientific interest, although the data base is still scant.

But if it bears on subjects we fear, like earthquakes, even painstaking background projects can be blown out of proportion. A recent example from Southern California went from an intriguing journal article to \"we're all gonna die\" TV stories in the space of a day. Maybe it will help you spot the next time this happens in the Bay Area.\u003c/p>\n\u003cp>\u003c!--more-->\u003c/p>\n\u003cp>The article, published in the prestigious \u003ci>Nature Geoscience\u003c/i> on June 26, presented the fruits of years of heat and tedium on the foul waters of the Salton Sea, in southernmost California. The Salton Sea occupies a sinking basin, the Salton Trough, that would rather be part of the Sea of Cortez except that the Colorado River has built a delta that dams it dry. As the river wanders over its delta, draining sometimes south and sometimes north, it periodically creates a geologically temporary lake in the Salton basin that has filled and dried out many times in the last few million years. (\u003ca href=\"http://www.youtube.com/watch?v=4RHu2h5CF9s\">A short video\u003c/a> by the University of Redlands illustrates the process.) \u003c/p>\n\u003cp>The repeating lake is known as Lake Cahuilla, and the Salton Sea is today's version of it. The Salton Sea is actually a terrible blunder, formed in 1905 when an irrigation canal tapping the Colorado River burst its banks and flooded a huge area of farmland in the dry bed of Lake Cahuilla. The breach was eventually fixed before the reborn lake could drown everything from Mexicali to Indio, but floods continued to be a problem until Hoover Dam was built upstream 30 years later.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>The Salton Sea covers up the southern end of the San Andreas fault, and that's where our science story begins. A research team from Scripps Institution of Oceanography crisscrossed the drowned land in a small boat with a state-of-the-art CHIRP sonar system. They mapped a swarm of short faults running from the end of the San Andreas toward the end of the Imperial fault lying to the south—a tectonic configuration called a stepover. Here's the figure showing how it all fits together.\u003c/p>\n\u003cp>\u003cimg src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2011/06/saltonmap1.gif\" alt=\"salton sea tectonics\">\u003cbr>\n\u003csub>Tectonic setting of the Salton Trough and Salton Sea.

The correlation is imperfect, but intriguing: every time the lake was reborn in a flood, the stepover faults gave way, and half of the recent mega-quakes coincided with stepover quakes. To connect the dots further, the researchers said that \"at least one of the last three dry-basin floods coincides with an earthquake on the SSAF (southern San Andreas fault).\" In their cautious words, \"We propose that loading by (Lake Cahuilla) may have induced failure on faults beneath the Salton Sea that, in turn, has the potential to trigger an earthquake rupture on the SSAF.\"\u003c/p>\n\u003cp>That's all ingenious science (seismic oceanography, in the desert!), but not news. To get news takes a press officer with a nose for a hook, and the hook is that the SSAF hasn't broken in some 300 years when we might (given the recent record) expect it to happen more often. Has our failure to let Lake Cahuilla be reborn held off triggering the next Big One? Well, has it?? \u003c/p>\n\u003cp>That question is something for geologists to wave their arms about at meetings and parties, not hold out to the world as a sure thing. But between the paper, \u003ca href=\"http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo1184.html\">whose abstract is world-readable\u003c/a>, and the \u003ca href=\"http://www.eurekalert.org/pub_releases/2011-06/uoc--foa062411.php\">press release from Scripps\u003c/a> we can see the story begin to morph. It's a scattershot press release, meant to serve any news angle, that immediately confuses today's managed Salton Sea with wild prehistoric Lake Cahuilla. It includes a great hook, a quote about the \"overdue\" SSAF likening it to \"a woman who is 15 months pregnant.\" The quote is only part of the background to the science, just a tangential part of the paper itself, but irresistible to the troutlike mind of the news reporter.\u003c/p>\n\u003cp>First out the chute on June 26 was \u003ca href=\"http://www.signonsandiego.com/news/2011/jun/26/salton-sea-poses-big-earthquake-threat-southern-ca/\">the \u003cem>San Diego Union-Tribune\u003c/em>'s website\u003c/a>, where Gary Robbins immediately removed all scientific uncertainty in his first sentence: \"The Salton Sea east of San Diego is a deceptively dangerous backwater, hiding faults that repeatedly produce powerful earthquakes that jolt all of Southern California, says a new study by the Scripps Institution of Oceanography.\" \u003c/p>\n\u003cp>Later that day a Los Angeles TV station rewrote Robbins's story under the headline \"\u003ca href=\"http://www.nbclosangeles.com/news/local/River-Diversions-could-lead-to-Megaquake-124595454.html\">Mega Quake Around the Corner?\u003c/a>\" with the lead sentence, \"Man's interference with Colorado River floods that used to regularly flow to the Salton Sea may have 'stopped the clock' on a regular series of big earthquakes, setting the stage for a mega quake that could wreck Southern California, scientists said Sunday.\" The accidental flood of 1905 has become \"interference\" with regular flows to the Salton Sea, and the reasoning has turned upside-down: If we had let the Imperial Valley drown, Southern California's \"Big One\" might already have happened and been a few tenths of a magnitude unit smaller. How anyone wins under that scenario is not explained.\u003c/p>\n\u003cp>After a few days, more and better journalists weighed in. Some of them had actually studied the \u003cem>Nature\u003c/em> paper (as I have). Many, including \u003cem>Discovery News\u003c/em>'s Tim Wall, \u003ca href=\"http://news.discovery.com/earth/smaller-salton-sea-silences-seismic-shocks-110629.html\">apparently did not\u003c/a>. \u003cem>USA Today\u003c/em>'s Dan Vergano \u003ca href=\"http://content.usatoday.com/communities/sciencefair/post/2011/06/salton-sea-floods-flipped-earthquake-trigger/1\">did well\u003c/a>.

To connect the dots further, the researchers said that \"at least one of the last three dry-basin floods coincides with an earthquake on the SSAF (southern San Andreas fault).\" In their cautious words, \"We propose that loading by (Lake Cahuilla) may have induced failure on faults beneath the Salton Sea that, in turn, has the potential to trigger an earthquake rupture on the SSAF.\"\u003c/p>\n\u003cp>That's all ingenious science (seismic oceanography, in the desert!), but not news. To get news takes a press officer with a nose for a hook, and the hook is that the SSAF hasn't broken in some 300 years when we might (given the recent record) expect it to happen more often. Has our failure to let Lake Cahuilla be reborn held off triggering the next Big One? Well, has it?? \u003c/p>\n\u003cp>That question is something for geologists to wave their arms about at meetings and parties, not hold out to the world as a sure thing. But between the paper, \u003ca href=\"http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo1184.html\">whose abstract is world-readable\u003c/a>, and the \u003ca href=\"http://www.eurekalert.org/pub_releases/2011-06/uoc--foa062411.php\">press release from Scripps\u003c/a> we can see the story begin to morph. It's a scattershot press release, meant to serve any news angle, that immediately confuses today's managed Salton Sea with wild prehistoric Lake Cahuilla. It includes a great hook, a quote about the \"overdue\" SSAF likening it to \"a woman who is 15 months pregnant.\" The quote is only part of the background to the science, just a tangential part of the paper itself, but irresistible to the troutlike mind of the news reporter.\u003c/p>\n\u003cp>First out the chute on June 26 was \u003ca href=\"http://www.signonsandiego.com/news/2011/jun/26/salton-sea-poses-big-earthquake-threat-southern-ca/\">the \u003cem>San Diego Union-Tribune\u003c/em>'s website\u003c/a>, where Gary Robbins immediately removed all scientific uncertainty in his first sentence: \"The Salton Sea east of San Diego is a deceptively dangerous backwater, hiding faults that repeatedly produce powerful earthquakes that jolt all of Southern California, says a new study by the Scripps Institution of Oceanography.\" \u003c/p>\n\u003cp>Later that day a Los Angeles TV station rewrote Robbins's story under the headline \"\u003ca href=\"http://www.nbclosangeles.com/news/local/River-Diversions-could-lead-to-Megaquake-124595454.html\">Mega Quake Around the Corner?\u003c/a>\" with the lead sentence, \"Man's interference with Colorado River floods that used to regularly flow to the Salton Sea may have 'stopped the clock' on a regular series of big earthquakes, setting the stage for a mega quake that could wreck Southern California, scientists said Sunday.\" The accidental flood of 1905 has become \"interference\" with regular flows to the Salton Sea, and the reasoning has turned upside-down: If we had let the Imperial Valley drown, Southern California's \"Big One\" might already have happened and been a few tenths of a magnitude unit smaller. How anyone wins under that scenario is not explained.\u003c/p>\n\u003cp>After a few days, more and better journalists weighed in. Some of them had actually studied the \u003cem>Nature\u003c/em> paper (as I have). Many, including \u003cem>Discovery News\u003c/em>'s Tim Wall, \u003ca href=\"http://news.discovery.com/earth/smaller-salton-sea-silences-seismic-shocks-110629.html\">apparently did not\u003c/a>. \u003cem>USA Today\u003c/em>'s Dan Vergano \u003ca href=\"http://content.usatoday.com/communities/sciencefair/post/2011/06/salton-sea-floods-flipped-earthquake-trigger/1\">did well\u003c/a>. So did Chris Clarke \u003ca href=\"http://www.kcet.org/updaily/socal_focus/commentary/shaking-the-salton-sea-34796.html\">on KCET's website\u003c/a>. Charles Q. Choi \u003ca href=\"http://www.ouramazingplanet.com/san-andreas-earthquake-lull-flood-control-salton-sea-1679/\">did fresh reporting\u003c/a>, as usual, for OurAmazingPlanet.com. \u003cem>Science News\u003c/em>'s Devin Powell wins my prize for his \u003ca href=\"http://www.sciencenews.org/view/generic/id/331864/title/Floodwaters_may_trigger_fault_motion\">succinct, factual and well-written account\u003c/a>.

But still—if scary news comes up, look around the \u003ca href=\"http://geology.about.com/od/news/Geology_News_Sources.htm\">science mediasphere\u003c/a> and wait a few days before deciding what you think.

North America and the Pacific have about 2 inches a year of motion between them. The San Andreas proper accounts for the majority of that, but lesser faults in the Coast Range like the Hayward, Calaveras, Rodgers Creek and Maacama take up a large share too.

From state route 99 it's visible from a much longer stretch, but only if the conditions are right.
