Here is an ward winning video focused on the removal of 12,000 Navajo from their ancestral homes in Arizona. Navajos, like other native Americans, saw themselves as caretakers of the Earth which is why the effort to remove them from their land in 1977 was particularly offensive. Martin Sheen narrates the documentary. It's all on line in 7 parts here and is very interesting and engaging. I use parts of it for our unit on indigenous religions in North America. And here is a link to a Navajo creation myth.
