Contemplation on the Blue Oak Trail

Here, hiking the rolling hills covered in twisted, mossy oaks, contemplation comes easy. Nature whispers in our ear, or pounds us over the head, and says, "pay attention!"

Just feeling the crunch of the soil under our feet can wake us up from our detached slumber. Are we of this, or outside of it? The Blue Oaks are sleeping now. Perhaps they are dreaming in a way we can not know. If we allow that there is a correspondence with all things, we can imagine that their process of dormancy is similar to ours, in a way.

In the fall, deciduous trees like the Blue Oak lose their leaves in a process known as abscission. The trees reabsorb the nutrients from the leaf before starting a cellular process that detaches the leaves from the tree. 

As we drift off to sleep, we reabsorb the nutrients of our day. That which we gave out comes back to us. In our own abscission, we drop the facade of our posture for the embrace of the mattress. We are not the vibrant, colorful crown of our day. We become the bleary eyed structure that needs to rest and regenerate. The tree absorbs the nutrients from the leaves and stores them in its roots for later use. The nutrients and toxins of our day are absorbed too, and stored in our roots as we sleep, for later use. Will they allow us to grow, or will they weaken our structure?

Maybe we recognize a tangle of confusion, not unlike the chaotic flow of our own current of thought. We can see where thoughts change direction, break off, twist, turn and gather their own moss and momentum. 

Then, rounding a corner, we might see a crown that teaches us to stretch and reach in every direction. Even in repose, the slumbering giant still holds life delicately in its embrace. 

Often on the trail, we can meet trees that have lived, stretched, reached and grown, and now their shells are the foundation and nutrients for new growth and new life. And the tree is oblivious to this of course. It knows only its life. But now we can see that the sharing and growth continue long beyond the life of the structure.

A little patch of earth shows both decay and growth. The cycle is both visible and invisible, because profound changes are happening at every point along the spectrum of life. Trillions of bacteria nibble away at the leaves, breaking them down in to new structures of contribution. Mosses, fungi and lichen, along with green shoots, come out the other end of the process. 

All the while, the trees reach and explore. They twist and stretch to experience their own environment. 

There is nothing in isolation in nature. There is growth upon growth, and life and worlds live on small and vast scales. On the surface of a tree, we can see a whole new forest of moss and lichen, with little streams, and whole generations of spiders and other insects live and die here, knowing only this world.

We can see how easy it is to change our perspective. Perhaps we can learn how to focus on different views of the same scene. 

Maybe we can understand that the impact of a moment can be changed by simply looking at it differently.

Even at the surface level of observation, we can still enjoy and experience tranquility. We can see the gentle rolling slope of the hills, the vibrant green of winter grass, the lazy ramble of a hungry cow. 

Every observation is a gift, and can be experienced as a whisper or a roar. Nature speaks. Do we listen?

Don Edwards San Francisco National Wildlife Refuge - Mallard Slough Trail

Sometimes you feel a breeze from a thousand years ago, and it wakes you up to what once was, and what might still become. The native population once observed the bay skies clouded with millions of migrating birds. We can now see the descendants of those birds carrying on the migration, though in fewer numbers, in the Don Edwards San Francisco Bay National Wildlife Refuge.

Here, you can see giant brown pelicans float on by like ancient pterodactyls, and great egrets launch with effortless grace and power. The beauty of the refuge is that it allows nature to continue its patterns and processes in a protected space, and gives us a front row seat to the show.

The 3.3 mile Mallard Slough Trail  gives you access to a variety of habitat in the refuge's 30,000 acre space. There are 15 different types of habitat here, each one hosting a variety of different plant and animal species. Each season brings new life and opportunities for visitors. 

The trail is a wide, fire road size levee that navigates a wedge of the refuge. Occasionally, a big lumbering Caltrain commuter shuttle roars by along the west stretch of the trail, but the birds seem to be used to it.

There are man made islands in the refuge, and many of the birds roost and observe from these places. I hiked the trail in late afternoon, looking to watch the end of the day activities. Pelicans were flying in and settling on the islands. Sandpipers were whipping by like a fast moving cloud. Their movements seemed choreographed in advance, like a high speed flying ballet.

Gulls dropped lightly out of the sky to roost on little plate sized patches of mud. They cleaned and warmed as they watched the sun drop.

All along the way Great Egrets flew and flapped their giant wings and looked like slim white sheets on a windy clothesline.

On the western stretch of the Mallard Slough Trail, I looked up to see a big Brown Pelican coming in for a landing. Like a mirage, he just appeared before my eyes, and grew larger as he approached. 

As he came close, he took a look at me, then he banked to his left and posed with the blue sky behind him.

I really got the sense this Brown Pelican was observing me. You may notice a sense of wary acceptance of visitors from the birds. They were quick to launch and get distance as I observed them. Parts of the refuge are open to waterfowl hunters during certain times of the year, and my camera and tripod may have looked like something else to these birds.

Fortunately, I had a long enough lens to capture moments like this below. Among this group of Northern Shovelers, some were landing and some were taking off.

Nestled in the deep grasses are pockets of open water, and Shovelers drift and float about.

Approaching the end of the western part of the trail, I came across a Great Blue Heron standing with a pocket of Northern Shovelers. I stood for a while on the trail, waiting to see if he would move. He was off the trail to the right, just on the shore. He gave me a side glance and ruffled his feathers. I lowered my tripod off my shoulder, placed it on the ground and stood behind my camera. He lowered himself, and launched, cutting through the air with powerful downward thrusts of his giant wings. As he flew by me he let out a haunting jurassic screech.

And just moments later the last light of the day touched down, warming the roosting White Pelicans on one of the little islands.

There was last minute chatter and negotiation for space as they took their places to observe the sunset.

The sky had a campfire glow, with the cloud's orange flames dancing in the high winds.
