This tree had two planks cut out of it in the traditional Haida fashion. The Haida would remove extremely long, straight, thick planks from tall cedar trees without killing the tree. This basically involves cutting a notch at the top (using stone tools) and dropping a few rounded pebbles in behind the top of crack they would cut. As the wind blew and the tree swayed back and forth the pebbles would work their way down the tree until eventually – *pop* – out comes an enormous plank of wood.
Note the 171 cm human figure for size comparison.
