Follow-up on Sal del Rey

 

 

 

It’s a lake with no outflow and an underground, 4-million-ton, salt dome right beneath it.  The salt is from the Jurassic period.  This area was part of the Gulf of Mexico back then; that’s where the original salt came from.  This is not the only salt dome around here, it’s just the one that geological conditions exposed.  Salinity in the lake is 10 times that of the ocean.  Seasonal rainfall determines how wet or dry the lake is.  It’s pretty white right now.  We haven’t had a rain lately.
