Round three of this week’s geomeme of a picture-a-day (previous entries here and here) features halite, a.k.a. rock salt! Pink (or pinky orange) halite, to be more specific. The mine, run by American Rock Salt, is the largest operating salt mine in the United States (3+ million tons annual production). This pink halite is located in the mine wall ~1,400 feet underground, where it remains minus the football-sized chunk we removed for display in our department collection!
