How water makes rock
When calcium-rich springs flow up through the lake bottom, the calcium bonds to carbonates in the lake water. Together they form calcium carbonate, a type of limestone. This solid material builds on itself, gradually forming a tufa tower. When the lake level drops, the exposed tufa stops growing.

Fragile Rock?

Tufa may be a rock, but it is fragile; please help preserve it.
Law prohibits both climbing on tufa, and collecting it.

John admiring Mono Lake for it unique beauty.

Mono Lake is truly a treasure for generations.
