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.

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.

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.

Hot, Hot, Hot: an August Hike to Bear Canyon and Switzer Falls

Date: August 22, 2013
Place: Colby Canyon and Switzer Falls, Angeles National Forest, Los Angeles, California
Coordinates:  34.26633, -118.14570

Difficulty: moderate (strenuous when hot)Length: about 4.5 miles

Last time we've been to Los Angeles, our good friend there showed us around and took us hiking at Solstice Canyon. This time, he was going to take us into Angeles National Forest, to one of his favorite trails: the Gabrieleno Trail to Switzer Falls.
We met at the hotel where we stayed and drove in a convoy into the San Gabriel Mountains. It was a slow drive and our host stopped to show us the after effect of the fire that incinerated the area in 2009. That fire, started by arsonists, had claimed 3 human lives and consumed 650 square kilometers and was the largest in California's history until the Sierra fire of last summer had surpassed it.
Bear Canyon had survived that fire. Deep enough and wet enough, the vegetation there was spared. We parked at the staging area and started walking along the creek.
Blessed shade in a hot day: the trailhead. 
Even in mid-August, the creek was flowing. It was nice to walk in the shade where everywhere else was unbearably hot.
Ripples and Light
The heat didn't bother the lizards. They cherished it.



We met quite a few lizards along the trail. Some were gracious enough to let us photograph them.
 

Whenever I lifted my eyes and looked through the trees I could see the charred evidence of the fire. Such devastation, so close.

Near the water, though, the trees were vital-green, shrubs were blooming and birds were twitting. It was life as usual.
Poplars by the creek
I was actually surprised to see flowers this late in summer. They were right by the water, though.
Fleabane (Erigeron brewery)
The fleabane is local. The chicory is an immigrant.

The trail to the falls goes up the hillside, which meant leaving the soothing shade and get exposed to the blazing sun, enhanced by the albedo off the white rock. The vegetation changed too: we were now surrounded by agave, toyon and yucca.
Chaparral Yucca (Hesperoyucca whipplei)
One particularly pretty sight was the mountain mahogany, displaying its feather-like seeds in the blazing sunlight.
Mountain mahagony (Cercocarpus betuloides)
The feathered tails allow the seeds be carried in the wind. Until then they give their mother bush a very angelic look.

And another seed display that caught my eye: 
Hollyleaf Redberry (Rhamnus ilicifolia)
In this case the seeds don't go anywhere with the wind, but are carried off by birds who eat the red fruit. 
There were also dead, blackened trees all around. We were happy to go down into the canyon and be back in the shade.

A short walk along the second canyon and we found ourselves by a little pool at the bottom of the lower of the Switzer Falls. We were delayed but a little, when Papa Quail noticed this canyon wren displaying on a nearby rock:

But even the wren couldn't hold us long.  A few minutes later we were sitting by the cool of the pool.
The bottom pool of the lower Switzer Falls. 
The chikas were quick to dip their feet in the water. Papa Quail and I followed our guide and climbed to the upper pool at the top of the fall, which was a bit of a risky business. Grandma Quail stayed and watched the chikas.

We didn't go on to the upper falls. That would have been too much for our heat-exhausted company.
It was high noon and very high heat. It took a great mental effort to get away from the cool of the pool and head back up the exposed hill. The chikas were rebellious, which added to the naturally-difficult conditions. We were very fortunate though, to have our friend guide us on that trail. He knew exactly where to stop and show us another fantastic feature of that trail: the Echo.
Sorry, no echo photo, but that's the magic spot.
We stopped on that spot and for a good long break, stood there, yelling, howling and making all kinds of vocal expressions at the opposite canyon wall. The echo was so clean and impressive that we did it for quite a while. The chikas (all of us, really) felt much better after that stop. We continued back to Colby Canyon and up the creek.

I just can't understand why anybody would want to hike in Nature while carrying a loud boom box with them. Luckily, those we've seen (and heard for a long while) on the trail were going the opposite direction.
We were drenched in sweat when we got back to the parking lot. The trail is beautiful. I would love to hike it again. Probably not in August, though. But Spring Break is coming soon ...

Many thanks to my friend, Green Thumb, for sharing with us the Nature treasures of Los Angeles County and for his wonderful company!

Many thanks also to members of the California Native Plants Society for their help in identifying plans!
