Possible Native American baskets

I bought a number of baskets from an estate sale in Denver Co., which had a number of other southwestern item including Navajo weaving. I really don't know very much about Native American baskets and wonder if I would get some expertise / information. This particular basket is a tight weave and quite firm or ridged. Looks like a faint pale yellow & darker brown and a pale tan design. Doesn't remind me of Navajo baskets which I've seen. In any case anyone out their in Collectors Weekly land I would appreciate knowledge / any input you may have. Best.
