Geography
At Badwater, significant rainstorms flood the valley bottom periodically, covering the salt pan with a thin sheet of standing water. Each newly-formed lake does not last long though, because the 1.9 in (48 mm) of average rainfall is overwhelmed by a 150 in (3,800 mm) annual evaporation rate. This, the United States' greatest evaporation potential, means that even a 12-foot-deep, 30-mile-long lake would dry up in a single year. While the basin is flooded, some of the salt is dissolved; it is redeposited as clean crystals when the water evaporates.
A popular site for tourists is the sign marking "sea level" on the cliff above Badwater.

Famous quotes containing the word geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Ktaadn, near which we were to pass the next day, is said to mean Highest Land. So much geography is there in their names.”
—Henry David Thoreau (18171862)
“Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.”
—Ralph Waldo Emerson (18031882)
