Welcome to the blog of writer and musician Andrew Martin. Here I'll post original photographs and observations as I encounter the history and culture of the San Fernando Valley, the City of the Angels, Alta California and the far-flung Pacific Rim… but mostly the Valley.
I’ve learned this is wand buckwheat, Eriogonum elongatum. The wands wave in wild winds on wuthering heights…whereas, workaday wooly buckwheat is wont to wallow a world away, in washes and wadis:
CalFlora.net: Eriogonum – from the Greek erion, “wool,” and gonu, “joint or knee;” that is, wooly puffs on jointed stems.Fasciculatum – ‘the one clustered together,’ fascicular = in bundles or clusters.Sawtooth goldenbush, Hazardia squarrosa. Lopez Canyon is where I first marveled at these elegant Asteracea, waiting along the side of the road as if I were the parade they were lined up to see. They are so common, yet so erect and poised…as if a fleabane or back-alley dandelion got into a Swiss finishing school. Its prickly holly-leaf is the convergent evolutionary choice of many chaparral plants, to retain water and deter browsing. Convergence makes it easy to confuse all the weedy yellow asters and false dandelions. For instance, one kind of goldenbush is called grindelioides, which means “like a grindellia.” And there is a grindellia with holly-sharp leaves just like the sawtooths, called Grindellia squarrosa var. serrulata. I think below is an example of the latter. Anyway, they’re all lovely.
From CE Conrad’s 1987 US Forest Service field guide to chaparral. Note the taxonomy change: the genus was Haplopappus and the species was squarrosus, not squarrosa. Zheesh! Botanists.
“Medicinal Uses: The medicinal use of gumweed dates back to Native American and folk times and it was listed as an official drug in the United States Pharmacopoeia until 1960. The slightly bitter and aromatic tea may be used for bronchitis or wherever an expectorant is needed; as an antispasmodic for dry hacking coughs (alone or often combined with Yerba Santa). It is believed to desensitize the nerve endings in the bronchial tree and slow the heart rate, thus leading to easier breathing; it merits investigation as a treatment for asthma. The tincture is useful for bladder and urethra infections. Tincture or poultice may be used topically for poison ivy and poison oak inflammations. Other indications include bronchial spasm, whooping cough, malaria, other chronic and acute skin conditions, vaginitis and as a mild stomach tonic. Native Americans (tribes including Pawnee, Cheyenne, Sioux [Lakota and Teton Dakota], Crows, Shoshones, Poncas, Blackfeet, Crees, Zunis and Flatheads) used preparations of curlycup gumweed both internally and externally as washes, poultices, decoctions and extracts to treat skin diseases and rashes, saddle sores, scabs, wounds, edema, asthma, bronchitis, cough, pneumonia, cold, nasal catarrh, tuberculosis, gonorrhea and syphilis, menstrual and postpartum pain, colic, digestive ailments, liver problems and as kidney medicine. The fresh gum was rubbed on the eyelids to treat snow-blindness. Effects: stimulant, sedative, astringent, purgative, emetic, diuretic, antiseptic, and disinfectant. Primary constituents: Tannins, volatile oils, resins, bitter alkaloids, and glucosides Other uses: Ornamental- it produces flowers over along period, even when the soil is poor and dry; young, sticky flower heads can be used as chewing gum; leafless stems can be bound together to make brooms. Contraindications: The herb is contraindicated for patients with kidney or heart complaints. There may be concentrated levels of selenium as it is a facultative selenium absorber.” — http://ayurveda.alandiashram.org/ayurvedic-herbs/grindelia-squarrosa-gumweed
Jepson’s doesn’t cite the common name for this flower, which is curlycup gumweed. (Maybe they were too embarrassed to mention it.) One might choose to chew the sticky flowers as gum; it’s also called Tarweed.
The View is reeling these days from the fast-paced, hectic, thrill-a-minute, presto–chango world of local geology. I haven’t been blogging because I’m too busy learning from the rapidly changing land. I feel like the boy Wart, being given his lessons in Deep Time by old Merlin. Every time I set foot on a trail in this remarkable Valley, puzzled by its mysteries — suddenly, there, in this hillside, or that chasm, or lying at my feet, I find a stunning new revelation of whatever point of ignorance I’ve been working my brain around. Which then brings up a hundred new questions! I’ve broken a couple computers web-searching Chinese papers on “convergent accretion wedges.”
Mostly I’ve been baffled lately by “mineralization,” that strange alchemy that apparently creates lead, zinc, copper, silver, gold…and pyrite and molybdenum and arsenic and graphite and uranium and all the rest. It’s apparently a phreatic process that is dependent upon fine changes in the water table. Iron, sulfur, and carbon dissolved in water deep under the mountains periodically boils or bubbles or cold-seeps up through the rocks (or, sands, it turns out…remember gold nuggets in creek beds?). When the pressure drops or the temperature or acidity become too much for it, the water vapor trapped in the rocks goes pffft! up a long spout of the loosest conglomerates; and the metals and salts dissolved in the water precipitate out over or into the cracks of the surrounding rocks, where, if the type of country rock sitting there is right, makes more al-chemistry take place, creating more and more amazing minerals.
This process, I have been reading about but couldn’t comprehend in the slightest! Maybe you can’t either, to read that paragraph. But I found a demonstration on the surface, just a few hours after it happened, and I was so excited I must share it with Patient Reader. I won’t explain further, just bear in mind the above facts, and accept that geology is now and didn’t happen in the past. View on.
Trail on top of left ridge up Sugarloaf
This geologically wonderful Viewpoint — wonderful west
…wonderful east. Hallo, what’s that gleaming in the path?
Yes, a fools’ gilded dandelion. I may have missed the sulfur cloud by minutes. They can kill hikers!
I became instantly irate about the obvious prank vandalism of kids with spray-cans — loathing as I do the graffiti appearing on rocks EVERYWHERE these days, especially with the kids out of school during COVID. Trying to fool people…! But then again, it’s right where mineralization, I think, has been happening. What’s further up the path? How’s the griffone?
I had come there looking to see if the griffone was still there. Was it? Yes…
9…side vents to mud volcanoes).
Wow —fresh coating of lacquery-coppery mineral wash!
The vent is the lower crack with the burnt twigs. To the left is murmuring sand from carbonated water or boiling steam. It blew the stream of fluid right under the extruding gneiss vein, which got washed and transformed by that coppery-green-gold finish, like the rocks on the ridge. Fluid is venting from the crease right where the trail meets the slope. The theory is, since the road cut interrupted the flow to the dome, the spot just in the crease of the road was the first place this highly pressured deep earth fluid found an opening to low surface air pressure, where it went poof! leaving the heavy minerals sprayed on the rock and sand — exactly like a kid with a spray can! In this case I’m pretty sure that what I found is chalcopyrite, the chief copper ore, and along with iron pyrite, one of the true “fools’ golds.”
The brassy coppery-greeny-gold of fresh pyrite!
Of course, the real fool finding fools’ gold, is the fool who, finding pyrite, sells his claim thinking it’s worthless. The savvy prospector buys it, for he knows pyrite and gold — and silver and copper — all take the same steam elevator. These pyritey rocks are also nicely cooked with traces of many rare metals deep inside.
For a guy who has been blundering around lately collecting mineralized ore samples to pound out and pan down looking for a few gold flakes…a process I DON’T EVER WANT TO REPEAT…
…I’ll take the fools’ gold, and the free lesson in Golden State geology, picked up off the trail side float. Gee whillikers, watch this space. Marvellous and strange things are happening in the Valley, and the View is onit!
