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, 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. When conditions are right, bright pink halophilic (salt-loving) archaea spread across the salty lakebed. Also, on especially hot summer days when ground temperatures exceed 150° F (66 °C), water is driven out of the hydrates on the lakebed creating a muddy brine. More commonly, periodic winds stir up noxious alkali dust storms that carry away as much as four million tons (3.6 million metric tons) of dust from the lakebed each year, causing respiratory problems in nearby residents.

Famous quotes containing the words current and/or conditions:
“The current flows fast and furious. It issues in a spate of words from the loudspeakers and the politicians. Every day they tell us that we are a free people fighting to defend freedom. That is the current that has whirled the young airman up into the sky and keeps him circulating there among the clouds. Down here, with a roof to cover us and a gasmask handy, it is our business to puncture gasbags and discover the seeds of truth.”
—Virginia Woolf (1882–1941)
“To get it right, be born with luck or else make it. Never give up. Get the knack of getting people to help you and also pitch in yourself. A little money helps, but what really gets it right is to never—I repeat—never under any conditions face the facts.”
—Ruth Gordon (1896–1985)
