The postcard and aerial photo below it show the Raft Lake cut which drained water from Raft Lake into Finlayson Lake. Many thanks to Brian Jackson and Terry Perrier for information and to Brian for the aerial photo.
"Rock Cut on Water Diversion Scheme, Steep Rock Iron Mines, Atikokan, Canada".
This postcard was mailed in 1957. The image was taken from the internet.
This photo shows the same area in 2002 with the Raft Lake dam in the foreground and Finlayson Lake in the background. The postcard photo would have been taken from the middle left of this picture looking straight down the cut.
