Crystal Power
The vast, surreal salt flats of Badwater Basin change constantly. Salt crystals expand, pushing the crust of salt into rough, chaotic forms. Newly formed crystals ooze between mudcracks, sketching strange patterns on the surface of the salt flat. Passing rainstorms wash off windblown dust and generate a fresh layer of blinding white salt. Floods create temporary lakes that dissolve salts back into solution, starting the process all over again.
Intense Concentration
The source of Badwater's salts is Death Valley's drainage system of over 9,000 square miles--an area larger than New Hampshire. Rain falling on distant peaks creates floods that rush ever lower. Along the way, minerals dissolve from rocks and join the flood. Here, at the lowest elevation, floods come to rest, forming temporary lakes. As the water evaporates, minerals concentrate until only the salts remain. After thousands of years, enough salts have washed in to produce layer upon layer of salt crust.
Sodium Chloride--better known as table salt--makes up the majority of salts on Badwater Basin. Other evaporative minerals found here include calcite, gypsum, and borax. |
