Vagabonding across the 39th Parallel is an informal exploration of the geology of an interesting slice of the American West that I followed in July. Our rules were simple: see something new, or see something we'd seen before, but in a new way. We had been to Mono Lake many, many times (our previous visit was only a few days earlier), but in all our visits we had never spent the night or watched the sun set there. We grabbed some sandwiches at the Whoa Nellie Deli and parked on the near by hill top to watch the twilight envelope the barren Mono Lake basin. Click on the panorama picture above to see what we saw...
What a wasteland! It's dry, so there are vast areas of nothing but sagebrush. There's the lake, but the lake is so salty that no fish can live in it, just fairy shrimp and disgusting brine flies and their wiggling grubs. Nobody goes sailing or swimming in the scummy water. It's a worthless piece of real estate...
During the ice ages, glacial meltwater filled the fault basin, and the water overflowed into the adjacent basins, eventually flowing into Death Valley. The lake was 600 feet deeper than it is today, and covered a much larger area. As late as 1940, the lake was 45 feet deeper than it is now.
Migratory birds discovered Mono Lake thousands of years ago, and found the fairy shrimp and brine flies a rich source of protein to sustain them on their long journeys. As more and more wetlands disappeared along the coast and in the Central Valley because of human development, the Mono Lake area became an ever more important stop on the migratory flyways. Dozens of bird species (and many millions of individual birds) depend on this lake for survival. What is worthless to humans is life itself to the birds.
Mono Lake Committee is a good source of information on current issues.
What is the value of a place? If one tries to put a monetary value on a landscape, many places would be deemed worthless. Mono Lake basin once supported a modest agricultural economy, but the Great Depression destroyed the economy in the region, making it worthless enough for Los Angeles to move in. How many places across the country face similar choices...especially in today's economy? Surely it wouldn't hurt to build just one more dam here, or to build another housing development on farmlands, or drill another natural gas fracking well? It's a difficult issue of course. We have to have the homes, the energy, and the water. But who is looking out for the air, the water, the soil, and the other intangible values of a landscape that ultimately make life possible?
By the way, I bet you could pick up some cheap farmland in Texas right now...it's ripe for development.
What a shame that the state of California has decided to close their part of the lake, Mono Lake State Park, because the legislature can't see their way to an agreement to fund the park and 69 others that are slated to close next year. Maybe we can sell the worthless land to someone who can profitably develop it?
Anyway, what a beautiful, peaceful sunset, with the moon rising over the Mono Craters. Despite any misunderstandings about my title for this blogpost, Mono Lake is a treasure, one worth protecting.
