While in Juneau Alaska on Mt. Roberts we were shown these tree carvings. They are carved in to live trees. One is a Raven and, the other is an Eagle.
The Tree Carvings are known as culturally modified trees. It is an ancient custom of the Tlingit People. One of the purposes of the trail markers was for identifying different clans’ rights to use a certain trade route. Always placed on spruce trees, each carving is made without endangering the tree, which creates a protective seal around the carving that discourages insects and diseases from penetrating the surface.
The carvings were created by a Tlingit Carver, Rick Beasley. The three trees on Mount Roberts were created in 1997, however the trees are hundreds of years old.
