Upper view of Rapidan Dam at Rapidan, Minnesota, on the Blue Earth River. Note to Miss Louisa Bartels of Chicago, Illinois; postmarked Good Thunder, Minnesota
Finishing work of putting on the top blank of flashboards at the upper dam. The Mississippi River is full of ice and slush, which hampered the work. The Great Northern Depot is visible in the background.
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.
