From Wikipedia, the free encyclopedia
Cheshire is a county in the north west part of England. A long time ago, about 220 million years ago, there was rock salt that was put down in this area. This happened during the Triassic period. Long ago, water from the big ocean came into the land and made a line of marshes with salty water in a place now called the Cheshire Basin. When the water in the marshes went away, it left behind big layers of salt that turned into hard rocks over time.[1][2][3]
