An 1847 travelogue by a visiting British geologist
A Canoe Voyage up the Minnay Sotor; with an account of the lead and copper deposits in Wisconsin...2 vols. by George W. Featherstonhaugh.
This is Featherstonehaugh's popular account of his 1835 explorations in Wisconsin and Minnesota, one of the most colorful and opinionated of the early travel accounts of our state. His official scientific report is also excerpted elsewhere at Turning Points.
