EXPLORING THE SALT MINES UNDER LAKE ERIE
In October I led a trip with Geologic Cognition Society into the salt mines almost 2000 feet under Lake Erie. This was in preparation for our exhibit at SPACES gallery in Cleveland Ohio which opened on January 29th. Details about the show are here.
This deposit is over 300 million years old from when the Great Lakes region and much of upper North America were covered in the shallows of a Silurian tropical sea. The coral reefs at the floor of this shallow sea fossilized and turned to limestone which formed a solid basin for the salt deposit to form over time as the waters evaporated. Time passed, glaciers came and went, and the salt deposit was covered with glacial till and rock. Here are some study shots I took of the salt deposit inside the mine. I used these during the production of the salt chamber that we installed in the vault at SPACES. Take a peek:
If you're in Cleveland between now and March 25th (2016), be sure to stop by SPACES, it's open to the public and is free to see the show.
