Bird's-eye view taken from Church Hill of Lanesboro power dam built over the Root River in 1868. It was constructed on a foundation of solid stone and anchored at each side by rock bluffs. Houses and various village buildings are seen on north side of river. Photo taken by unknown photographer and later copied by Bue.
This drawing was done in the aftermath of October 5, 1869, Eastman Tunnel collapse. A tunnel connecting Nicollet and Hennepin islands collapsed on that day causing the need for considerable repair to be done to Hennepin Island and St. Anthony Falls. The repair work was finished in 1884, creating a protective apron over the falls.
