EVAPORITE TUFA, MONO LAKE. CALIFORNIA, USA
These ice-berg like features in and around California's Mono Lake
are TUFA deposits. CARBONATE rich waters flow into the lake from
the surrounding mountains. The carbonate is PRECIPITATED from
SOLUTION in the warm waters of the lake to form these TUFA deposits.
The process is complicated by the movement of VOLCANIC GASES through
the lake waters.
MONO LAKE has been the focus of a major ENVIRONMENTAL ISSUE since
water was first diverted from the lake by the L.A. AQUADUCT (carrying
water to Los Angeles) some 30 years ago. The lake level dropped
drastically, many life forms died and ENVIRONMENTALISTS took up
the cause. Now, as after a recent court judgment, more water is
allowed to flow into the lake and the level is rising again.
