Tufa...

Mono Lake is an ancient lake, that was being drained for many years to provide water for the Los Angeles area.  As the lake drained the Tufas were exposed.  A few years ago, the water has been allowed to start refilling the lake.  In about 12 years or so, these tufas will again be under water...
