Deep beneath Lake Erie is a massive salt mine, stretching from Edgewater Beach to Burke Lakefront Airport and north about 3 miles. Cargill Deicing Technology extracts as much as 4 million tons of salt each year from the maze of tunnels, to sell as far as Minnesota and Massachusetts. The salt is leftover from a giant inland sea that 400 million years ago stretched from Michigan to New York. You could delve anywhere in that swath to find salt. Photos: Marvin Fong | cleveland.com

Head deep underground to see Cleveland's Cargill salt mines. The mines, which take up 16 square miles of space under Lake Erie, exist 1,800 feet underground. And every day, more than 200 employees mine an average 12,000 tons of salt. 🖊️/📷: Jacob DeSmit https://clevelandmagazine.com/in-the-cle/the-read/articles/step-inside-the-cargill-salt-mines-under-lake-erie | Cleveland Magazine
