2 summers ago I toured museums in Canada that represented Native Americans
and found that the Head Smashed in Buffalo Museum in SO. ALberta is one of
the best.  There are many innovative exhibit tecniques used and I feel your
visitors would learn alot.  Also recommended would be the Secwepmec Museum
in Kamloops, BC on the Shushwap Reserve.  It is a small museum, but is
very nice and even has an outdoor component called the "heritage park"
which is essential to demonstrating a holistic view.>
