Exactly what story is it they want told? The one where they scrounged for food every day, then beat corn into meal on flat rocks so they could bake tortillas? Or the one where invading tribes captured hundreds of their men for blood sacrifices to their moon gods? Or that time they invented gunpowder, printed language, and the wheel? Oops! Never mind those.
Besides, what history do they have, except what they've been told? Most didn't even have any written alphabet, so couldn't pass along any history except by word of mouth.
As Mariner said in #2, the Pacific Coast Indians had it quite easy as food was abundant.
