Yesterday I stopped to look at the canoe tree in Finley
I'd guess this park was built in the early 1970s before the legislation came in for scarred trees to remain in situ.
The canoe tree must be old as the heartwood has hollowed, which also means one can't get an idea of whether a stone or steel axe was used.
I like the accompanying mural that gives an idea of the processes used by Aborignals to make a canoe from a cutting of River Red Gum bark.
