Great Law? Great Tree? (2010 Native American dollar)

Dentuck

Which is it --- the "Great Law of Peace" or the "Great Tree of Peace"?

The Mint's literature uses both. The coin's legend says LAW.

Not sure what the coin's law says. . . . maybe LEGEND?

Prolly pagan symbology. The tree represents the law, or the law is treelike, or the tree gave the law, or the law shades us, etc.
