Ancient Mono Lake
The most unusual feature of Mono Lake are its dramatic tufa towers emerging from the surface. These rock towers form when underwater springs rich in calcium mix with the waters of the lake, which are rich in carbonates. The resulting reaction forms limestone. Over time the buildup of limestone formed towers, and when the water level of the lake dropped the towers became exposed.
