We took a road trip between 1/23 and 2/11 2007 and one of our stops was the famed Mono Lake on the east side of the Sierra Nevada.  I have been to Mono Lake over a period of  50 years but until now had never taken 3D photos of the famous tufa towers.  You may enjoy them.

To view each image in 3D, stare at the pair and slowly cross your eyes.  The two images will merge into a third image in the center which will be in 3D.  Sometimes it helps to tilt your head slightly left or right.

Tufa is essentially common limestone. Typically, underwater springs rich in calcium  mix with  lakewater which is rich in carbonates and a chemical reaction occurs resulting in calcium carbonate—limestone. The calcium carbonate precipitates around the spring, and over the course of decades to centuries, a tufa tower will grow. Tufa towers grow exclusively underwater, and some grow to heights of over 30 feet.

Because the water supply along the east side of the Sierra is siphoned off to Los Angeles, the lake is lower than its historical height, thus many of the tufts are on dry land.
