Never seen it before until now. There is a lake near the Spanish town Torrevieja. Near the lake stand several white mountains of salt. They look like snow mountains or piles of white cement. Some are bigger and taller; whereas some are tiny. I’d wonder what happen when it rains; or when someone buried by the salt. Are they really coarse salt crystals? Why did it only cost little for a big bag in the past and a lot for a little bottle now?
