Tilden Between Seasons: A Spring Hike of Laurel Canyon/Wildcat Peak Loop

The Golden Gate, and Bridge. 

Dates: March 1 and 12, 2016
Place: Tilden Regional Park, Berkeley, California
Coordinates: 37.908997, -122.264978
Length: 2.5 miles
Level: moderate (strenuous when muddy).

Time was pressing. In two weeks' time I was to lead a 4H hike and the destination I selected for that hike turned to be unsuitable for that group. I needed to come up with another nice trail and, as always, I found what I needed within the vast selection of East Bay Regional Park District hiking trails.
Tilden Regional Park east of Berkeley is beautiful, accessible, and high in popularity. I have taken the 4H Hiking Project there before, but this time we would do a different trail: the Laurel Canyon/Wildcat Peak loop in Tilden Park Nature Area, near the visitor Center and Little Farm. This 2.5 miles hike involves a good measure of elevation change that was just right for this group. As it turned out, however, the 4H'ers (as well as their adults) had to deal with a much greater challenge, brought on by the weather.

On the first day of March, however, I hiked there by myself, to check out this loop. I had hiked it before (sadly without my camera, after having left it at home in my hurry), but that was a while ago and I needed a refresher. Besides, it was a perfect day and there's no need for other reasons to be out in the woods. 
The first challenge when hiking with children in an area with popular attractions is to avoid unnecessary distraction. While that trail officially begins behind Little Farm, I knew I would never get the kids to even begin the hike if we were to start there. So I started my hike behind the visitor center, where a wide dirt road ascents into the eucalyptus grove and meets Laurel Canyon trail in a safe distance from the attraction. 
At the trailhead
I started the hike in a Eucalyptus grove but soon transcended into the native East Bay live oak/laurel forest. The Laurel Canyon trail is narrow and ascends uphill in a series of long switchbacks that go between some pretty cool looking trees.
Coastal Live Oak (Quercus agrifolia)
The trees house a myriad of other creatures. Some just like the high grounds. Other live off the tree. literally.
Oak Gall
March 1, the day of my solo hike, was sunny and warm. Wherever I looked there was new spring growth. Wherever the sun seeped through the canopy the new trees were rushing upward to fill it in.
A Baby Coastal Live Oak (Quercus agrifolia)
The deciduous buckeye trees were budding with new spring foliage, lovely bright green. Easy to forget that merely 3 weeks before they wore bare gray back.
Budding California Buckeye (Aesculus californica)
But although spring was already in, winter wasn't about to leave just yet. The soil was damp still, and new mushrooms were growing on the forest floor.

And as far as spring bloom goes, it was still the time of the ephemerals: the first flowers of spring.
Milk Maids (Cardamine californica), with poison oak in the background. 
All throughout my ascend in the woods I could hear the cheerful sound of creek water flow. Eventually I go to cross it. On the previous time I had hiked that trail that little creek was dry but now it was running happily between the trees.
Laurel Canyon
The trail crosses a few tributaries of Laurel Canyon. A couple are transversed by small wooden bridges. Others are crossed with a wide hop (or a wet wade). In certain places the way down or up the creek is too steep to hold a stable trail and man-made steps were built to maintain possibility. These little stairways look like something out of an ancient fairytale.
Stairway to Heaven
Two weeks later on my March 12 hike the middle of these was covered with foam near the trail crossing. I don't know what caused it. My thought was that the rushing water beat the decomposed proteins of some dead animals in the stream, but I don't really know. I only saw it there and it was quite thick foam.
Foam on Laurel Creek
March 12 was a rainy day. Actually, rainy is a bit of an understatement. It was a sorry day. The rain came down on and off throughout the hike but the wind blew strong and cold. That hike came after almost 3 months break in Hiking Project activities and neither me nor the members had any thought of cancelling it because if the weather, so we geared up and hiked that trail despite the rain and the wind.
As always when I go out on a stay-indoors-weather I meet other creatures out, who flourish in wet conditions. Banana slugs, for example.

East Bay soil is dark and heavy, and when wet it transforms into thick mud that is both very sticky (to soles, clothing and skin) and very slippery. Hiking uphill is twice as strenuous when the mud cakes on the soles of the shoes and glues you down to the trail. Hiking downhill is even more challenging because the tendency to slip and fall multiplies 100-fold.
We were chugging along on Laurel Canyon when the chaperon in the back called me to stop, and when we gathered around him he showed me this grub that he found on the trail. It was huge (in insect scale) and it wiggled helplessly on the man's hand. Its entire body looked soft and juicy (from a bird's point of view) but it had a hard head with nasty-looking mandibles that looked like they could cut through anything. I wondered if that could be the forest's big nemesis - the grub of the boring beetle.

Another, even more fascinating find, was the witch's butter fungus that was growing off some dead logs along the way. The wetness had turned the orange color even brighter, giving it a sheen that made it look like something that flew out of someone's nose. Needless to say, the children were quite amused by this fungus. 
Witch's Butter 
Higher up near the ridge the trail leaves the forest and enters chaparral area, where sunshine is abundant (on clear days, of course). On March 1st it was very abundant indeed. Glistening in the sunlight - the leaves of one of the common California Coast residents: the Poison Oak.
Poison Oak (Toxicodendron diversilobum)
I reached the top of Laurel Canyon Trail and turned left onto Wildcat Peak trail. I was still ascending toward the peak, emerging from the chaparral to open, grassy areas where many wildflowers were blooming.  
Blue Dicks (Dichelostemma capitatum)
Blue dicks and blue-eyed grass were the most common wildflowers up by Wildcat Peak, dotting the grassy patches with blue and purple. 
Western Blue-eyed Grass (Sisyrinchium bellum)
At the Wildcat Peak there is a stone circular wall with benches - the perfect plave for a rest stop. And there is a fantastic 360° view of the Bay Area.
View to the southeast: Mount Diablo
Although Wildcat Peak isn't very high it is prominent and the views stretch far. But I didn't have to look far to see the San Pablo Reservoir.
View east: San Pablo Reservoir
To the north: San Pablo Bay and Mount Tamalpais in Marin County, where I recently had an amazing spring hike. Seers through 'The Mist' might be able to detect the Titan's Castle and Atlas holding off the sky :-)
View northwest: Mount Tamalpais
Heading this post is the photo of the view west, of the Golden Gate and the famous Golden Gate Bridge. That photo and the other view images above were taken on sunny March 1st. By March 12, the view was very different: it looked as if the world ends at the edge of the forest.
View west: Foggy Gate
The upper part of Wildcat Peak Trail goes through human-height chaparral, and I was making my way down that trail, taking care not to trip on the narrow ditch cut through by the runoff water.

That slope also features open grassy areas reach with wildflowers, among them the California Poppy: our State flower.

A colorful patch on the hillside was dominated by Indian Paintbrush. Facing the west sun gets the best wildflowers out.

A brilliant silver bush lupine on the edge of the trail. I arched around it to try and get the best view, with and without the Bay in the background.

Most of the wildflowers were closed two weeks later, hiding their blossoms from the downpour. The lupine was still blooming strong, the flowers advanced now to the inflorescence tips.

The slope of Wildcat Peak Trail is steep, and on March 12 was very, very muddy and slippery. Me and the 4H members were inching down slowly careful not to slip on our behinds. A couple of the kids got into a sour mood but others seemed to flourish in the wetness, just like the trees.

Not all trees could take the storm. Freshly fallen trees, some were already previously dead, littered the forest floor.

The lower part of the trail is back in the forest. In that area the grounds is back to the forest undergrowth wildflowers. A common one I saw there is the non-native forget-me-not.
Broadleaf Forget Me Not (Myosotis latifolia), invasive non-native
The forest ground is the neighborhood of the wood rat. Their twigs nests were all around, little mounds of sticks, each homing one rat.
Woodcut nest
They also build penthouses: safety nests up the trees. There they escaped from ground dangers.

I kept walking down, looking around. One of the forest shrubs if the chaparral currant, its pretty blossom lightens up the dark forest under story. 
Chaparral Currant (Ribes malvaceum)
On my March 1 solo hike I continued all the way to Jewel Lake: a small, old time reservoir that is now a beautiful wildlife-teeming pond.
Jewel Lake
Many insect flew over the water, and a happy black phoebe kept looping over to grab them, then going back to its favorite willow branch to preen and keep watch.

Not as many waterfowl as I had expected: A sole common mergancer who managed to escape my camera, and a single male bufflehead duck who wasn't bothered at all by my attention.
Bufflehead
A turtle was enjoying a sunbath. I would have gladly joined in, but at that point I was already hurrying back to the trailhead. I needed to be on time to pick up the chikas from school.

I wasn't too much in a hurry to miss the little boardwalk detour through the riparian wetland.

The dominant vegetation about the boardwalk were willow bushes, many of them had already finished blooming. The photo below was taken on the higher elevations of my hike.
Arroyo Willow (Salix lasiandra) 
Needless to say, on rainy March 12 the children were in no mood to make a detour through the lake. Wed, muddy, and weary from the difficult descend, they all opted to go straight away to the Nature Center. There, after a few minutes of warming up, they were gathered along with some other kids by a local EBRPD naturalist who gave them a little presentation about pond life, and then took them outside to a little pond behind the center for some hands-on exploration. I thought they ewould be too tired to go but to my astonishment they all donned their coats and run outside into the rain as if they completely forgot how they complained about the wetness just minutes before :-)
They dipped nets at the pond and fished all kinds of insect larvae and other microscopic life and brought samples back inside to view by the indoors microscope (the newt was left outside. The rest of the animals were promptly released after the viewing).

As I watched the children completely absorbed and fascinated by these microscopic creatures, enough to not mind at all the rain and mud, I thought about the barriers that our comfy homes put between us and Nature, and how easily we tend to dismiss the joys that come with the rain for the comfort of our dry homes. Don't get me wrong - I like to keep warm and dry as much as anyone. It's just that there's so much so see and appreciate when it rains that can make rainy outings a true pleasure to experience and to share with children. And that girl in the pink boots and her friends who went out in the rain to meet and engage Nature, they are the future of Nature appreciators in California, and the world at large.

A Strong Spring in Tilden

Date: April 17, 2013
Place: Tilden Regional Park, Berkeley, California
Coordinates: 37.88947, -122.23466
Length: about 2.5 miles round trip
Difficulty: Strenuous

The hills of the south-east Bay Area are slowly turning brown. Naturally, I had the impression that spring is waning. Today, however, I went for a hike in Tilden Regional Park and found to my pleasure that in the north-east side of the Bay Area, spring is still going strong. Therefore, I am quickly writing up this post and pushing it too to the top of the queue. Bay Area residents! This is the perfect time to go visit Tilden.
Along with some fantastic hiking trails, Tilden also has many family attractions. It is one of the most visited parks of the East Bay. Finding a quiet trail, therefore, could pose a challenge. Being one who normally shies away from crowds I chose to hike the Arroyo-Vollmer Peak loop on the south-east region of the park and is enough removed from its main attractions.
Uphill view from Arroyo Trail

The Arroyo trail has a decent upgrade, which got me panting before too long. Wildflowers along the path gave me the perfect excuse to stop for frequent photo-breather stops.
The lower part of the trail goes along the Arroyo Creek (now dry) and is fairly shaded. As it goes up the tree groves become fewer and far between and the hillsides are covered with chaparral. As soon as I left the shade the wildflowers started paining the trail side.
Blue dicks (Dichelostemma capitatum)
One of the shortcomings of the internet is that it doesn't transmit scents. It is impossible for me to deliver here the sensual delight of walking among some of the most fragrant plants that can be found in the Bay Area. Here are examples of some of these plants (most are not in bloom at the moment, and not all I could identify). Please click on the photos for a large view.

Salvia spp. 



Sagebrush (Artemisia californica)
Pinapple weed (Matricaria discoidea), invasive


Artemisia douglasiana








Fennel (Foeniculum vulgare), invasive.

California Laurel (Umbellularia californica)












But there were plenty of wildflowers all around. Most of them I've seen on the upper part of the Arroyo Trail.
Plantain (Plantago lanceolata), invasive.
Hill Morning Glory (Calystegia subacaulis)









Just before meeting the Vollmer Peak Trail there is an open grassy area patched with a few lichen-coated rocks. The entire area was dotted with colorful wildflowers and I was hopping giddily from one patch to another, taking snapshots of the magnificent coastal spring. 
Dwarf Checkerbloom (Cidalcea malviflora)

California Poppy (Eschscholzia californica)









Many of these wildflowers which paint the East Bay hills are, in fact, invasive weeds that immigrated here from the old world and took a powerful hold in this land, much at the expense of native species. The botanical landscape of the Bay Area today is very different than what is used to be before the European settling. For better or worse, they are now an integrated part of the local plant communities.
Vicia villosa
A patch of clover (Trifolium hirtum)
This includes the huge Himalayan Blackberry patches all along the trail. They were in full bloom and, in a couple of month I plan to return to Tilden with buckets for the booty.

My original plan did not include going all the way to Vollmer Peak. I could not resist the temptation, however, and took the trail that connects to the paved road that leads to the peak. Along that road I saw the thick pouches of nascent cow parsnip inflorescence. On that day I could not find one in full bloom.
(Less than a week after I returned with the chickas 4H group and the roadside was white with their large umbrella-like blossom).
Cow Parsnip (Heracleum lanatum)
The road to Vollmer Peak also provides a viewing opportunity to the east.
Briones Reservoir







There are large antennas at Vollmer Peak  and a nice, shady tree overlooking to the east. Someone thought it a good idea to hang a swing on that tree and I spent some time rocking on that swing like a happy little child.










A waved to the familiar Bay Area land mark: Mount Diablo. Now should be the time to visit Mitchell Canyon to see the endemic globe tulips in bloom!

Mount Diablo
The view from Vollmer Peak to the west was no less spectacular:
San Francisco
I was lucky that day. On my return trip with the group the fog was still in the air and visibility was very poor.
The Golden Gate Bridge
Ocean liners move south past the Oakland Embarcadero
I didn't see much wildlife on this hike. I could hear birds all around but they were very shy and didn't come out to the open. Except for this robin that stood his ground on the Vollmer Peak road:

I backtracked my footsteps to the Vollmer Peak Trail and started descending. There were plenty of wildflowers along that trail too. Some in small patches, like the yellow Mule's Ear, and some in wide carpets. like the bright orange Scarlet Pimpernel.
Coast Range Mule's Ear (Wyethia glabra)
Scarlet Pimpernel (Anagallis arvensis)

Further down the trail enters chaparral area where the dominant color was the bright yellow of the invasive Scotch broom:
Scotch Broom (Cytisus scoparius)
The trail goes past the fire station and near the steam train depot. At that point it enters a large Eucalyptus grove. There, in the thin, filtered sunlight I found the shy-blue Forget-Me-Not and the bold-yellow Euphorbia.
Forget-Me-Not (Myosotis latifolia)
Euphorbia oblongata





Eucalyptus is also a very fragrant plant and its smell dominates the air on the Vollmer Peak Trail. It was close to the parking lot, though, where I could enjoy the gentle scent of this mint:
Less than a week after this hike I returned to this trail with the chickas 4H group. There were many flowers still, also some that were at the beginning of their season. The lupines, however, where laden with heavy pods. For these, as well as other ephemeral plants, spring is ending.

Summer (and berry season) is right around the corner.
