The Onondaga Nation is petitioning the Organization of American States (OAS) for land rights to Onondaga Lake, a notoriously polluted body of water in Central New York State. The Onondaga Nation is one of six nations of the Haudenosaunee Confederacy (Iroquois), and Onondaga Lake is the sacred site where Gayanashagowa, the Great Law of Peace, was established.
