The Empire Prairie

Large portions of Dane County and Columbia County, Wisconsin were once covered by a 200-square-mile prairie, now known as the “Empire Prairie.” When I first started researching this ancient prairie, I was surprised by how little information I could find about it. So using archival maps, land survey data, and historical documents, I’ve reconstructed the Empire Prairie to the best of my ability. Below the map is my four-part series investigating the Empire Prairie. This is a work in progress, so expect more installments as time permits.
