A Different Kind of Hill: Brushy Peak Regional Preserve

Dates: February 3, and February 14, 2015
Place: Brushy Peak Regional Preserve, Livermore, California
Coordinates:37.747054, -121.708995
Length: about 2.5 miles
Difficulty: easy to moderate

I am always on the lookout for new places to hike. Ever since I took on leading our 4H club's Hiking Project I've been rapidly expanding my coverage of Bay Area trails. And one of my latest discoveries is Brushy Peak Regional Preserve, north of Livermore.
Brushy Peak
North of Livermore there are rolling hills of open grass savannah. What is not yet built is used for cattle grazing, and the hills on the east are also installed with numerous wind generators. In between these hills nestles a small clump of hills with a very different look: they are rock and dotted with dark oaks. The prominent one can be seen briefly when traveling through Livermore on I 580. This is Brushy Peak.

I saw it on the map and made a plan to go there and check it out. My plan didn't go quite as I hoped and I arrived at the preserve with only two hours to hike before having to leave. So I chose the West Side loop Trail, which is only about 2.5 miles long. That trail turned out to be perfect for our families group so in less than two weeks after I was there again, hiking that same loop with our 4H Hiking Project.
West Side loop Trail
Both these hikes took place in February. The weather was sunny and the temperatures ambient. A couple of months later I would have called it perfect. It was, however, over a month since the last raindrop had fallen there, and there was no cloud in sight. On either day.
Right by the trailhead there is a cattle gate and a tiny pond. The area of that pond is closed to trampling: efforts are made to restore native vegetation there. On my first hike there was a lovely couple on the water: a pair of mallards sifting through the mud for morsels.

Behind the pond - an intersection of trails. Taking the right turn I headed straight to Brushy Peak.
The hills along the way are covered with low grass which, on February, was vibrant green. It was also marked with many holes connected by narrow trails and looked like the face of the moon, only green and considerably more inviting.

It is the work of ground squirrels, of course, of which I so many on both hikes. They would run to and fro, and occasionally stop and sit up on their hind quarters, stare at me and yelp loudly.
Ground Squirrel
Squirrels wer not the only creatures shouting from the grass. Numerous meadowlarks were about, and they too were very vocal.
Not that I don't like squirrels, but I like much better the meadowlark song.
The grass was almost devoid of flowers. There were a few, however, and they did get my attention. On the early part of the trail those were the buttercups.
Buttercup (Runanculus sp.)
Children's eyes are closer to the ground and in general, they are much more attentive to little things than adults. On the second hike, on that same trail segment, they found a hole in the ground with a frog inside. After much begging I got them to move aside a little so I could try to photograph it.
A surprise on the way
Below Brushy Peak is another, bigger pond. Man made, of course.

The waterfowl didn't care that the pond is man made. They enjoyed it to the fullest.

Up close the slope of Brushy Peak shows its variety of terrain and vegetation. The trail doesn't go to the peak itself but squeezes between the two rocky, oaky hills. Turning in that direction, however, would have taken me on a longer loop for which I didn't have the time on that day. So I admired the oaks from further away and continued on the left fork of the intersection, up the grassy hill to the west.
Oaks on rocks
Half way uphill I turned and looked behind me. The pond lay below, not very far, but already looking tiny.

Up ahead on my left, on the grassy slope, a sole live oak, neatly trimmed at grazing height parallel to the ground.

Nearing the top, another tree caught my attention. Also alone, with very little foliage. It looks like a guardian of ... I'm not sure what. Guarding the spirit of the hill, maybe :-)

Over the top and looking south there should be a view of Livermore. On both my hikes, however, visibility was terrible and a blanket of thick smog covered the city.

Visibility to the east was somewhat better. I could see the front line of the wind generators.
At this point I would also like to add my personal distaste of this form of energy generation. IMHO, the environmental damage caused by these wind generators outweighs the benefits by a large degree. Whatever amperage that is produced by these unsightly turbines is not worth the bird carnage they cause, estimated at over 300,000 a year, including many eagles and other birds of prey.

Looking back north I could see the very tip of Brushy Peak just above the horizon. There is no public trail to the peak itself, and getting there requires a special permit from the East Bay Regional Park District.

The hilltop isn't barren as it looks. The squirrels, for example, peek around the few rocks that dostick above the soil.

And a few dots of color show here and there. A representative of our State Flower, for example.
California Poppy (Eschscholzia californica)
And also a few mustard plants that were just beginning to bloom. Mustard was brought here by the Spanish missionaries who seeded this plant as they made their way north from Mexico. Along with other Mediterranean plants that were brought on purpose or as casual hitch-hikers, the mustard took hold and became a dominant part of the California coastal landscape of today. In springtime, large yellow mats of blooming mustard appear on the green East Bay hills. As pretty as this sight may be, it is a vivid reminder of the profound change brought on this land by the early European settlers.
Black Mustard (Brassica nigra). Highly invasive.
It is a mild slope descending back to the first trail intersection. The trail meanders on the soft ridge, allowing for plenty of opportunities to appreciate the little critters that live between the grass blades.
A spider hole
There, just a few yards away, I noticed a bird species I've seen before only at the very top of Mission Peak Regional Preserve: the beautiful Horned Lark.
I saw it on my solo hike, when I didn't bother to bring my large zoom lens along. Needless to say, when I returned with my group and a proper birding lens, this bird was no longer there.
Horned Lark
Another creature I only got to see once, on my solo hike, was this golden squirrel. It was sitting behind the tiny pond as I was closing my loop hike. I had such an unusual color it almost glowed on the grassy background. Never before have I seen a squirrel of that color, and it was the third time that day that I sorely regretted not bringing my zoom lens along. (I didn't mention previously the golden eagle that passed above me, of which I have no decent photo).
On the following group hike I promised a prize to the person who sees this golden squirrel, but that only lead to everyone pointing at each and every squirrel along the hike. They're all very special, I'm sure (to their mothers, anyway), but none of them was golden.

This loop trail is perfect for a relaxed family hike, although probably better during cooler seasons. As I left the park I sent  longing look behind: I still have on my checklist to hike that longer, more alluring eastern loop trail.

To Exist or to Cease: Mono Lake Wonderworld

Mono Lake, South Tufa, October 2011
Date: January 4, 2015
Place: Mono Lake, South Tufa, Lee Vining, California
Coordinates: 37.938774, -119.027170
Length: about 1 mile
Level: easy

Mono Lake is one of those places that are so unique that they look and feel almost outlandish. Located on the eastern end of Yosemite's Tioga Pass and right on Route 395 that parallels the Sierra Nevada range from the east, Mono Lake is a popular stop for sight-seers and has become a regular stop for us too. Whenever we travel in that direction we make the time to visit this strange and beautiful place.
Mono Lake, January 2015
Like Point Lobos State Reserve, whenever we visit Mono Lake we always enter at the South Tufa and walk that one interpretive loop that meanders between the tufa formations, along the lake shore and back through the savannah. Although there are other trails in the area, somehow we had never explored them. Yet.
Our hike at Mono Lake as captured by Papa Quail's GPS last January. (We didn't go in the water. It's just a GPS extrapolation between points.)

But Mono Lake isn't just a beautiful park. It is also a delicate ecosystem that supports numerous California native plants and wildlife, some are specially adapted to its unique environment. It is also an essential stop for migratory birds who take the eastern Sierra route and a breeding place for the California Gull and other fowl.

It also provides enchanting views. And while no man-made structure can be seen in this view, it is very much a man-affected scenery. Hauntingly beautiful and painful to know the process that brought it about.

Mono Lake is an alkali lake. It has no outlet and the salts carried into it by the Eastern Sierra rivers concentrate in the lake water and create a high-salinity (alkali) water environment. This environment supports a very specialized set of organisms, such as the brine flies that can be seen on the lake shores like vibrant dark ribbons, shimmering along the waterline. These flies are not bothersome at all. They are not interested in people whatsoever and when approached - they scatter about in clouds that make a landing just a few feet away.

The flies' larvae, as well as brine shrimp,  are rich bounty for seagulls, ducks and other waterfowl.

And so are the flies themselves.

There are no fish in Mono Lake. The water is too alkali to support fish. Area osprey must get their catch in nearby streams. Perhaps it was a tourist too.

Carbonate minerals concentrated in the lake's water precipitate to form a special limestone formation called Tufa.

There are plenty interesting tufa on shore but the prettiest formations are sticking out of the water. Their reflection in the calm, blue water may have some contributing effect :-)

But the thing is that, naturally, this tufa should not have been exposed at all. 74 years ago, as part of the natural water system of the area, Mono Lake's water level was higher than the tufa seen today.

Mono Lake is a poignant example for the damage done by human resource exhaustion. Fortunately, it is also a groundbreaking case for conservation efforts and scaling back of resource use.

Mono Lake is at the lower part of Mono Basin. Into it would normally collect water coming down the Eastern Sierra of Yosemite. But 'normally' was before the city of Los Angeles claimed rights for the Eastern Sierra water.

Water rights in California is a messy business about which I will not expand here. In short, late 19th century population growth in Los Angeles and the rising demand for water beyond what is naturally available locally. The city officials then led a dirty campaign to acquire the land of Owens Valley (south of Mono Lake) and drain its water via aqueduct to the city of Los Angeles.
October 2011
But the city continued growing and the draining of Owens Valley was not enough. So in 1941 the Eastern Sierra rivers that were leading to Mono Lake were also diverted into the Los Angeles Aqueduct, and the drying of Mono Lake had begun.
January 2015
With its tributaries diverted, Mono Lake water level dropped and its salinity mounted to a point endangering the brine shrimp on which so much of the local ecosystem depends.
January 2015
As water levels continued to drop, land bridges were formed and the former lake islands were connected to the surrounding land. That gave land predators access to bird breeding colonies, which were decimated.
Mono Lake and its ecosystem were on a fast track to death.
January 2015
In 1978 the Mono Lake Committee was founded and the fight for the life of Mono Lake had begun. Through a series of law suits and intense education efforts water diversion was scaled back. On 1994 the court ruled that the water level of 1963 (a sign on the trail marking that spot) was set to be achieved within 20 years from the court ruling.

The Los Angeles Department of Water and Power fought the court rulings, both actively and passively (by delaying implementation). Today, 21 years after that court ruling, the sign marking the 1963 water level is still very far from the shoreline.
And the battle rages on.

Human history is full of accounts of wealthy, powerful societies taking control of remote water sources and diverting them to the demise of local communities and ecosystems who depended on that water. The story of the Los Angeles Aqueduct is no different: with financial backing from city bonds and the use of dirty politics and immoral exploitation of early California water rights laws, the city of Los Angeles and the surrounding areas now depend almost entirely on water channeled from hundreds of miles away.

The Los Angeles metropolis is the one of the Nation's largest, second only to New York. Wikipedia cites Mediterranean climate as a primary reason, but the city's growth would have never come about on local water sources. The Los Angeles Cost of Living is much more than housing, education, and and city services. It is also the horrific price paid by the communities and ecosystems who lost their aquatic lines of life in the process, without concent or any real say on the issue.

It is also a dangerous state for Los Angeles to be at - the complete dependence on remote water sources. With the continuing drought and no foreseeable decline in the demand for water there may soon come a time when water restrictions will make Los Angeles a much more difficult place to live.

Past mistakes cannot be undone, but erroneous water policies can be amended. The use of modern technologies can make water recycling and reuse a major source for much of The City's water needs. Also, Los Angeles does have a large source of local water - the Pacific Ocean. With the combination of ocean desalination and water recycling, Los Angeles can become water independent. The City of Angels can give life back to the places its been draining all these years.
It will take public education and will. It will take visionary and moral policy makers. I truly hope it will happen before the catastrophe, inevitable if things would be allowed to continued unchanged, strikes.

The area surrounding Mono Lake is a low scrub that is home to many animals. Rabbits can often be seen sneaking between the shrubs, and many birds sound their songs from within the thicket. Sometimes though, they do make a bold appearance.

Most of the year Mono Lake area is hot. Could be very hot. Last January though, we gorse our noses there. And yes, that white stuff on the ground ... not salt.

Walking about Mono Lake is truly a timeless experience. No deadline, now set destination. We would meander slowly with or off the trail, stroll along the shoreline, pose for a photo with the tufa, look for wildlife and absorb the serene beauty and calmness of the place. 
October 2011
And without noticing, we would be heading back to the gravel parking lot, ready to bade farewell and move on.
On our last visit to Mono Lake, a California gull in full breeding colors was waiting for us on the gravel near the car. It didn't approach us or begged for food or anything. It just stood there, waiting. Waiting for what, I'll never know, because after taking its photo we got into the car and drove off.

Like many times before, last May we took visitors to see Mono Lake. My mother and her friend, who knew the place only from photos before. They were duly impressed. I was flat to have insisted on going all the way down the Tioga Pass to show them this magical place. But now we were facing the long way back across the mountains to Sonora, where we were to stay the night.

Coming out of Mono Lake, there is some choice as to where to cross the Sierra Nevada range. During summer time, there are more mountain passes to chose from. After our latest visit to Mono Lake we chose to return west via the Sonora Pass (CA 108), which diverts from CA 395 north of Bridgeport. The area east of the big rise has wide, green (at summer) pasture fields. Driving along these fields I noticed large, blue flowers in many clusters in those fields. As I noticed some closer to the road I immediately pulled over: they were irises.

Papa Quail Grumbled. It has been a long day already and he wanted to be back at our hotel in Sonora as quick as possible. One glance at the roadside fence though, and he was quickly out of the car too, camera in hand.

We remained there in that anonymous place for a few long moments during which I tried to capture the vastness of that iris field and failed miserably (the day light was already waning), so I settled for decent individual flower shots of the iris, and also of the pretty gooseberry bushes that were blooming along the fence.

After getting satisfaction with the yellow-headed blackbirds Papa Quail turned on the other blackbird species that sat on the fence and turned out to be the tricolor variant of the red-winged blackbirds. 

If making your way east on CA 120 to see the high Yosemite, make the extra effort and drive all the way out of the park and down to Mono Lake. It will extend your day but a little. It will extend your spirit a lot.
