Tam Cam November 2019




We finally got some rain the last week of November. I knew I'd be out of town during that week of Thanksgiving, and I knew rain was in the forecast. Nevertheless, I risked leaving one of the trail cameras near a pool of water, figuring no amount of rain was going to raise the creek enough to cause any problems. And when I went to retrieve the camera, both the pool and camera looked pretty much as they had the week before, except that now there was a little mat of soaked bay laurel leaves on top of the camera. Did they fall from above? I removed the leaves and opened the camera to find that water had gotten inside the battery compartment, and the cam would not power up.

My first thought was that these inexpensive Foxelli trail cams had failed their first real test of exposure to a drenching rain, but when I checked the other two cams that had been out in the same area, they were fine. What I think happened is the level of the pool rose just enough during the night of the big rain that the camera went underwater. Maybe the mat of bay laurel leaves didn't fall from above, but actually settled on the camera after floating above it. The microSD card was pretty much toast, but did record several very short video clips. Although the camera is set to run video for 20 seconds after snapping two still photos, each clip only recorded for about 3 seconds. No stills were recorded at all.

The only other snag is that somehow the datestamp in one of the cams changed to July! Something I'll have to double-check when I swap batteries in the future....

Early in the month I placed two cams down by Redwood Creek between Muir Woods and Muir Beach, and finally caught my first possum. The possum has a brief tussle with a raccoon at one point. A large tree branch falls into the middle of the frame without tripping the camera, and a gray fox scampers through the frame with what appears to be a brush rabbit in its mouth. The other location turned up raccoons, a fox, a coyote, and a bobcat that clawed the base of a tree. I had set that cam on what I thought was a game trail that crosses a seasonal creek, but all the animals were caught using the dry creekbed itself as their preferred route.

I pulled the Redwood Creek cam about halfway through the month since I wasn't sure I'd still be able to reach it if it rained enough to get the creek going.

My favorite footage comes at the beginning and the end of this month's video. After seeing the route a bobcat took in October, I set up two cams in the hope of catching closer views of it ambling up the creek bed, then jumping up on the fallen tree that spans the creek. I ended up capturing a fox with the two-cam set-up instead. The bobcat did finally appear near the end of the month, but it took a slightly different route up the creekbed, and after it jumped up onto the fallen tree it turned in the opposite direction that I'd planned for, so still no bobcat close-up.

Thankfully the wet season has finally arrived. Walking in the woods finally feels and sounds right. The loamy forest floor is spongy again, and footfalls can be silent. Out on Bolinas Ridge, though, the hills are still as brown as can be. I made a smartphone snap on the last day of the month, after checking on the trail cams:


After checking on the cams earlier in the month, my wife and I did a little hike that took us past a swing that someone has roped to a bay laurel on Bolinas Ridge. The bonus was finding a trio of musicians playing into the wind:





And finally, on the way back from our Thanksgiving stay in Mendocino, we stopped for veggie burgers at Amy's Drive Thru in Rohnert Park. I snagged a cup lid and a fork that are stamped as "compostable" and have set them in my little urban garden beneath my native hazelnut tree (I put the deer antlers in the ground when I planted the then-tiny hazel several years ago; it's now taller than I am). I'll be interested to see how the plastics fare over the winter, especially compared with a hazel leaf:



* ONE YEAR LATER *


I pulled the fork and drink lid out of the garden soil on Nov. 25, 2020. Neither seemed any worse for the wear after being buried in the dirt for a year.



Both items could have been re-used in virtually new condition after being rinsed with water. Nice lesson showing that compostable isn't the same as biodegradeable.

Reading Nature


October Tam Cam

I was kind of surprised when I realized I'd gone a whole year without posting anything. I didn't know I had that much self-restraint! Ha ha. And now that two years have passed, I'm kind of champing at the bit again, although I have no clear idea of what I want to say or what I want to photograph, especially within the time restraints of work and trying to rationalize the carbon footprint of driving a motor vehicle to chase new inspiration, the same things that brought me to a halt two years ago.

What is a nature photographer to do when the human world has become a pot of frogs slowly bringing itself to a boil of environmental catastrophe?

I work for an environmental organization and am immersed in the bad news every day. The solace of photography used to help me cope with it all, but then the solace came to feel like futility. I figure that's just depression talking, but I haven't quite figured out the counter-argument.

Although I've been doing very little "serious" photography the last couple of years, I've been immersed in a great deal of inspiration through other means, sometimes nearly to overflowing. What I haven't been able to do is dye my photography in that basin of joy. The images always fall short of what I want to convey, even though nature herself always delivers.

One thing I've learned in the last couple of years is that if I want to lighten the load, I don't just need a smaller camera. I need to go into nature with no camera at all and enjoy even what can't be photographed, capturing images that only I will ever see, and which last only in my own brief memory. I accept that the images will fade. Fading away is just part of the beautiful sadness of being alive in this world, and renewal is always just around the next bend.

As photographers we venture forth into the vast and wild realm of potential to extract a single image, an essence. Maybe the image isn't even important as long as we capture the essence. Like the alchemists of old, we come to realize that the gold we seek is not the ordinary gold, but something of much greater value.

And I guess I'll just leave it at that.

A few months ago I was thinking about replacing a trail camera that had gone belly-up a year or so ago, at first just to see what the critters were up to these days when they'd come around my back yard here in San Francisco. I've long wanted to put more than one camera out there since no single placement could give me the angles I wanted, but even the cheapest trail cameras have run a couple hundred bucks.

Until now!

Now you can get a Foxelli trail camera (and maybe other brands), outfit it with rechargeable batteries (I use Panasonic high-capacity eneloop pros) and micro-SD card, for under a hundred bucks. All of a sudden I had four of these things, and I soon satisfied my curiosity about the back yard critters. My main gripe about these cameras is that the audio is completely useless since the microphone is muffled up against the battery compartment. I know from previous cameras that audio, while usually not important, can sometimes add significant interest to a trail cam's video capture. (The other gripe is micro-SD cards. Because they're too small to easily remove and grip with my fingers, I keep forceps in my kit bag when I go to swap cards.)

I got the cameras back in August and although I still like to put one in the back yard now and then, I mainly like to put them out in the wild. The trick is to put the camera somewhere unlikely to capture or be seen by humans, yet still in a place that will capture wild animals. In all the years I've used camera traps, I've accidentally caught people several times, but of the minority of those people who actually noticed the camera, only one has actually stolen it (I suspect it was too near someone's dope-growing site). Luckily it was one of these inexpensive Foxelli cameras. I was almost as disappointed to lose the pricey rechargeable batteries as the camera itself.

One of the things I've always liked about doing regular photography is just slowly poking around and looking for subjects and compositions to spark my interest. With trail cameras I slowly poke around looking for good placement spots. Either way, I get to enjoy stealthily skulking around in the woods, reading nature. And after a week or two have gone by I'm eager to get back up there to find my cameras (grateful they're still there), and to get the SD cards home so I can see what I captured.

I don't know if I'll feel drawn to get back into regular photography anytime soon, but until I am I'll settle for the vicarious enjoyment of being in the wild through my camera traps despite having to be at work all week.

One thing I've already noticed is how attached I've become to the places I've been setting the cams despite their not-very-photogenic ordinariness. When I'm up there in person I've spooked a great horned owl from an oak tree and realized it was probably the same owl that showed up in my camera trap. A deer that came out of the woods to check me out one morning is probably the same one that knocked over one of my cameras. I'm reminded to appreciate the fact that the mountain isn't just a place to see animals, but a place those animals call home, and somehow the camera traps let me share in that sense of belonging-with-the-land.

Sit Spot

* * *

Compare with http://jwallphoto.blogspot.com/2017/09/gone-to-seed.html

I recently found a great little sit-spot on some big rocks in the mostly dry bed of Cataract Creek. It’s close to the trail, within earshot of passing hikers but out of sight behind the woods and walls of the ravine. There’s a small pool of water at the base of the rocks that the local birds know about, and if you sit still enough, a Pacific wren might skitter down for a drink just a few feet below you. Bigleaf maple, Doug fir, and tanoak make up most of the canopy, with hazel and huckleberry filling in some of the gaps on the forest floor. The space in between is fairly open, luminous in the morning sunshine, and the view from the sit spot gives the feeling of being suspended in that space.



Rippling unseen through the space was a placid soundscape of acorn woodpeckers cackling in the distance and an intermittent breeze breathing through the leaves overhead, all of which conspired to make me conscious of the atmosphere itself. If you think about it, the motion of gases in the air around us is as much a part of Earth’s fluid dynamics as the motion of water around fish in the ocean. And like the ocean, the fluid of our atmosphere isn’t composed of just one thing, but actually a myriad of different gas molecules, pollen grains, fungal spores, bacteria, and so on. The air actually has mass, or weight, and even hiking through it creates friction. With a little imagination you can picture yourself practically breast-stroking up the trail.



As you swim, think about the fact that while you are immersed in that sea of gas molecules, pollen grains, fungal spores, volatilized plant resins, and dust motes, that all of it is entering your body with every breath you take. Waves of light strike your skin and impart their warmth. Waves of sound strike into your ears and, like light entering your eyes, initiate a cascade of electro-chemical signals in your central nervous system, much of which rarely, if ever, escapes your subconscious realm. There is no sharp line dividing you from the atmosphere. In fact, there is no sharp line dividing you from everything that is.

Resonant Frequency

* * *


So I was sitting on the edge of the world out at Chimney Rock this morning, thinking about a couple of books I've been reading: The Tale of the Dueling Neurosurgeons by Sam Kean, and The Brain That Changes Itself by Dr. Norman Doidge. At the base of the cliffs, elephant seals wriggled and belched while a rising tide began to reclaim their small sandy beach. Flocks of brown pelicans glided like arrows above lines of waves rising to meet the rocky shore. Looking out to sea, the Farallon Islands were the only point of reference in the silvery haze along the horizon. Large swells rippled inexorably toward shore on a low frequency, like pond ripples moving in slow motion.


According to the authors of these books, a hundred billion neurons and trillions of synapses were at work inside my skull as I sat cross-legged atop that coastal bluff in the morning sun, hardly moving a muscle. A bouillabaisse of more than a hundred different molecules, chemical compounds called neurotransmitters, were ferrying information within a forest of axons and dendrites, and the lunk with the camera bag hardly even noticed.


And that was just the stuff going on in my skull! The whole of my organism was respirating and metabolizing and doing countless other duties thanks to thirty-trillion cells that know more about chemistry, physics and biologyabout life itselfthan all the smartest scientists with all the latest technology in the whole wide world. And not only that, but whatever pebble fell fifteen billion years ago into the still and timeless void to get this surf party started, contained within itselffrom the strings that build the quarks that build atoms that build the molecules—every potential that makes our world and our lives possible.


Looking out at the swells resonating across the ocean, I could imagine tracing them back to their source, like a jungle explorer following the trails of wild animals toward some El Dorado, some mystical center, and it seemed in that moment that the point of emanation is what the old Chinese philosopher Chuang Tzu called "the pivot of tao," and that if you could say only one thing about that point before saying a second thing and contradicting yourself, it would have to be that it all began in a state of bliss.

That's right. All the crap emanating through time and space, everything that's good and bad, loving and indifferent, chaotic and orderly, had to start somewhere, and if you simmer it all down to its original essence, the last scintilla in the pan is bliss.

So put that in your pipe and smoke it.


On my way out to Chimney Rock along rutted roads and cow-burnt hillsides, I stopped briefly along the road to North Beach to photograph the setting harvest moon. While I was at it I noticed a flicker of movement on the periphery of my right eye. I turned to look and could hardly believe what I was seeing. A coyote at the top of a dune was leaping into the air as a pair of female marsh hawks made teasing passes just out of reach. It was like something from Alice in Wonderland. "Are they playing?" I wondered incredulously as I scrambled to change to a longer lens. "No," I answered myself, "there must be something at least halfway serious going on."

The coyote leaped three times that I saw clearly, but by the time I got the long lens on the camera and dialed up the ISO to get a decent shutter speed, the coyote and the hawks had spotted me spotting them, and they broke it up. It reminded me of a Far Side cartoon where animals are always doing something totally unexpected when the humans aren't watching.

Mortal Asclepias

* * *


I packed my camera gear up to Mt. Tam this morning to look for narrowleaf milkweed (Asclepias fascicularis), a lovely plant whose generic name honors the son of Apollo, god of medicine. I don't remember to look for it every year, but I last photographed it on Mt. Tam in 2011. The only time I ever saw or photographed a monarch butterfly caterpillar feeding on this plant that's so important to the life of monarchs, was 2003. There were no milkweed plants in their former haunts this year, not even at Potrero Meadow. I didn't see any jimsonweed either. I imagined a few seeds of both of these interesting and beautiful plants biding their time in the soil until conditions become favorable once again. Maybe next year.

UPDATE (9/26/17): I noticed my first blooming plum tree as I biked home from work today, which reminded me that a guy on the Marin Native Plants group on FB said the milkweed was blooming like crazy in Potrero Meadow back in late July, quite a bit earlier than usual. Shopping for yard plants at Sloat Garden Center last weekend I saw a monarch land on a plant and pointed it out to an employee who told me he'd found two monarch chrysalises just the week before. Yesterday afternoon I saw another monarch flutter by downtown, near Sue Bierman Park. It can't be good for monarchs to show up in fall, only to find the usual haunts of milkweed gone, having already bloomed weeks or months earlier.

Golden Asymmetry

* * *



A hundred years before I was born, Louis Pasteur wrote that the difference on Earth between things that have life and things that don’t is like the difference between a static photograph and a dynamic one:

“Most natural organic products, the essential products of life, are asymmetric and possess such asymmetry that they are not superimposable on their image,” he wrote. “This establishes perhaps the only well-marked line of demarcation that can at present be drawn between the chemistry of dead matter and the chemistry of living matter.”

When you compose an image on your screen or in your viewfinder, you notice that simply moving the center of interest away from the center turns a static (dead) scene into a dynamic (living) one. We think about, or maybe intuit, the “rule of thirds” when making a composition, but a more useful concept might be the “golden ratio” which does not draw a perfect circle, a perfect symmetry that ends where it begins, but a dynamic spiral with endless possibilities. 

As science has learned only recently, the universe itself exists due to an asymmetry between the matter and antimatter that were created together at the beginning of time. In those first moments of creation, matter and antimatter could have annihilated each other, but for some still-unknown reason they didn’t. Instead, about one in a billion particles of matter escaped to become the world we know and love.

Instead of going out in the crazy heat to shoot pictures I've been reading The Disappearing Spoon by Sam Kean. That's where I learned that life itself also depends on asymmetry, or what chemists call chirality. Kean led me to the Louis Pasteur quotation above, which in turn led me to wonder if science has figured out yet how life got started in the first place. Apparently it has not.

“If you think about the physical world, it is not at all obvious why you don’t just make more dead stuff. Why does a planet have the capability to sustain life? Why does life even occur? The dynamics of evolution should be able to address that question. Remarkably, we don’t have an idea even in principle of how to address that question….” – Physicist Nigel Goldenfeld in Quantamagazine.

It’s kind of fascinating to draw a line from a universe where matter got a foothold due to asymmetry, to a planet where life got a foothold due to asymmetry, to a time when human beings would roam the earth and find beauty in asymmetry, in a golden ratio that perhaps reflects an archetype of consciousness that’s as deep as Creation itself.

Pondering Sanskrit

* * *



As I stare into a clear night sky and ponder mysteries such as the existence of life on other planets, I recall that life almost came to an end on our own planet during the Permian-Triassic extinction around 250 million years ago, long before the more famous dinosaur extinction. Life mysteriously arose on Earth nearly 4 billion years ago, then gaily swam about for the next 3.5 billion years before evolving the ability to come out of the water and onto the land. So it was just about half-way between then and now that life’s experiment on Earth nearly came to an end.

I have a hard enough time acknowledging the ephemerality of my own life, but to realize that all life on the planet almost went belly-up is mind-boggling, not to mention heart-wrenching. We think our presence on Earth is inevitable because we’re here. Our memories are short. Like a gorilla in Rwanda who shares 98 percent of our DNA, we don’t think about millions or billions of years ago. We get into enough trouble worrying about the past and future of our own lives.

What if life’s great experiment had gone belly-up millions of years before human consciousness had ever formed? Before a human thought had ever been born? Before anyone ever needed to be reminded to “be here now” instead of living in a dream? Before quantum packets of starlight ever sparkled into a human eye and kindled an imagination?

Would the universe be void and meaningless without us? Without aliens on other planets who may have been shaped by their own near-miss extinctions? There is no such thing as 16 billion years ago, at least not in this 15-billion-year-old universe. What was the meaning of life before there was even a universe?

Some probability of human beings must have existed in that first spark some 15 billion years ago, the spark of creation itself. The alpha scintilla shaped itself into a sprinkling of gassy stars, some of which eventually burned through their hydrogen and helium and exploded into supernovas whose furnaces furnished the elements of life and scattered them about the universe. Let gravity pick them up. Let scientists put them in order, lightest to heaviest. H-He-Li-Be-B-C-N-O-F-Ne, and so on.

Like any other sentient creatures that may exist in that vast cosmos, we are made of the elements formed in supernovas, shaped into life by the universe itself.

“Tat Tvam Asi,” the Dharma says. “Thou Art That.”

Summer Air

* * *


I just read Caesar’s Last Breath, in which author Sam Kean makes science writing as fun as anything else you’d bring to Limantour Beach for an enjoyable summer read, with the difference that he imparts thought-provoking information in addition to relaxing entertainment.

One of the chapters is about a gas we all take for granted, a component of the air all around us, called oxygen. It kind of jams my gears to imagine living in the vast span of human history before oxygen was discovered, before its true nature was precipitated out of the chaos of thousands of years of phlogiston and swirling human wonder. It’s thought-provoking to be reminded that oxygen was discovered less than 250 years ago, and it’s entertaining to read about the people and their experiments which led to the discovery. Imagine trying to discover oxygen yourself. How would you go about it?



Every schoolchild knows we need oxygen to breathe, to animate our lives so we can do things like walk to Sculptured Beach at Point Reyes and take pictures of weird rock formations. It’s a rote fact that we don’t even stop to think about, but around the late 1700s, as Kean writes, “[Antoine] Lavoisier had articulated the connections between fire, oxygen, and breathing, declaring that breathing was a sort of slow, controlled burning in our lungs. It remains one of the most important chemical discoveries ever….”

Having already discussed nitrogen, which preceded oxygen’s introduction to the Earth’s atmosphere, Kean continues farther down the page that, “Oxygen and nitrogen are neighbors on the periodic table…, [b]ut if the buildup of nitrogen a few billion years ago gave our planet its third and most benevolent atmosphere, the arrival of oxygen inaugurated a fourth and much more explosive regime. Whereas nitrogen is non-reactive to the point of being comatose, oxygen is volatile, manic, a madman in most every chemical reaction. It actually poisons many forms of life, and caused the greatest crisis that life on Earth ever faced, the so-called Oxygen Catastrophe of two billion years ago….”



Wikipedia refers to this “catastrophe” a little differently. On one hand oxygen’s arrival caused a mass extinction, but on the other hand, “the Great Oxygenation Event alone was directly responsible for more than 2,500 new minerals of the total of about 4,500 minerals found on Earth.”

I wonder which of the many minerals that make the geology of Point Reyes so interesting owe their existence to the formation of oxygen some 2.5 billion years ago.

In Caesar’s Last Breath, Kean writes that “oxygen destroyed early life because it detonates so easily inside cells; yet when life learned how to control oxygen, that reactivity became its greatest asset.” Continuing in a more arch vein, he continues, “And given how much havoc oxygen has wreaked throughout history, it’s fitting that this element destroyed every chemist who had a hand in its discovery. It’s the Hope Diamond of the periodic table.”

A science book written with a novelist’s flair: now that's a breath of fresh air.
