ZZYZX (Soda Springs Ca.)

  The story starts tens of thousands of years ago, when the area was cooler and wetter.
 A massive lake called Lake Mojave covered the land. 
  As the climate warmed, the water evaporated, leaving behind a mineral/salt 
crust on the dry Soda lake and Silver Lake basins.
 Water persisted in the natural oasis, and can still be found there today. 
A natural spring system, called Soda Springs, was used by the Mohave and
 Chemehuevi people for many generations, and by the mid-1800s it was also used 
by early western explorers and the US Army. (From Website)
