164 Fragile sand tufa

Tufas form when calcium-rich spring water mixes with the carbonate-rich waters of the lake, creating these structures that grow beneath the surface. Exposed when L.A. diverted tributaries feeding Mono Lake into the CA aqueduct, this fragile Sand Tufa is at the mercy of visitors and has been disappearing rapidly. Lee Vining, CA.
