Mirabilite Pond
Mirabilite Pond is an alkali pond at a high elevation in the southern part of Antarctica's Hidden Valley, west of Koettlitz Glacier. The pond is located on the northern side of the ridge that bounds the southeast part of Hidden Valley. The feature was studied by U.S. geologist Troy L. Pewe in 1957–58 whose finding of a thin film of the white salt mirabilite (Glauber's salt) around the edge of the pond suggested the name.
courts ordered the city to pay $154,000. After an unsuccessful appeal to the state supreme court in 1941, LADWP built the Long Valley Dam, which impounded Lake Crowley for flood control.
Current conditions.
The lake is currently a large salt flat whose surface is made of a mixture of clay, sand, and a variety of minerals including halite, burkeite, mirabilite, thenardite, and trona. In wet years, these minerals form a chemical soup in the form of a small brine pond within the dry lake
