When Jeff and I took the kids on our great Historic Highway 395 road trip from Orange County, California to southern Oregon last June, with a couple nights’ stay in Mammoth, in addition to a stop at the Obsidian Dome, I also insisted we visit another site from my favorite childhood vacation memories — Mono Lake. My Clint Eastwood fanatic husband quickly supported the idea once he discovered that Mono Lake served as the filming location for the town of Lago in the movie High Plains Drifter.
Mono Lake is located off Highway 395, 13 miles east of Yosemite National Park and 30 miles north of Mammoth, near the town of Lee Vining. I can’t even remember how many times I visited it as a kid. It might have been just once. It might have been several times. But, what has always stood out in my memory is the Tufa Towers and dry (very low) barren lake.
The odd looking Tufa Towers are the primary reason most people visit Mono Lake. They are limestone formations that are formed and grow under water, some up to 30 feet tall. You can easily see the largest Tufa concentration in the South Tufa Area, which is part of the Mono Lake Tufa State Natural Reserve. Guided tours, as well as self-guided walks, are available in the Natural Reserve (admission is $3 per adult).
When we arrived here last summer, I was shocked to see so much water in the lake, because water levels were much much lower when I was a kid. I had expected to find the lake almost bone dry, only to discover that it now even supports boating. Obviously, I had not followed news of the region over the last few decades.
The reason that so many Tufa Towers were and are visible along the lake is because in 1941, the Los Angeles Department of Water and Power extended the Los Angeles Aqueduct into the Mono basin and began diverting all of the water from Mono Lake’s tributaries. This caused lake levels to drop to dangerously low levels — which was the case when I visited as a child; with 1982 showing the lowest recorded levels on record — and put the area’s ecosystem into peril.
Conservation efforts lead to a court ruling that started reversing this process in 1994, requiring that lake levels steadily climb until levels are restored to just below the 1941 mark. When that target mark is met, a large portion of the South Tufa Area will once again become submerged under water.
