300 MILLION YEAR OLD SALT ROCK

300 MILLION YEAR OLD SALT ROCK

50.00

This salt is 300,000,000-400,000,000 years old and was formed as a shallow Silurian sea was drying up. This rock is the part of that sea that didn’t evaporate into the air, it is the trace of what once existed. A huge basin of limestone made from fossil corals covers much of the Great Lakes region, this basin helped the ancient sea to concentrate as it dried up increasing salinity until all of the water was gone and a fifty foot thick slab of salt blankets the limestone bedrock from Northern Michigan down through Ohio to the Kentucky border where it meets a sandstone Aquifer, and over as far as Eastern New York. That salt deposit is covered with thousands of feet of glacial clay. This salt was mined in the salt mine pictured in the third picture. Add this special mineral to your collection to sit with something truly ancient and feel the weight of time. Note: this salt is not for consumption. Salt is a purifier and a preservative. You will receive one of these salt rocks* for your collection.
