We visited Karchner Caverns, near Benson, AZ. It is a limestone cavern discovered by two geology students in the 1970's. They convinced the landowner and the governor of Arizona to sell the land to the state of Arizona and establish it as a State Park. It helped that both the landowner and the governor had geology backgrounds.
