Rock Solid Salt
When Aaron brought us to visit the local salt mines we came across this. These are large puddles filled with water nor are they frozen; this is a picture of salt that has harden to the point of being ice-like. Now, contrary to the title the salt is not rock solid because if you step on it then the salt will crack, but it is still fascinating to witness the process of making either table salt or salt that is used for industrial purposes.
