Possible Native American baskets 2 similar look in construction.

I bought a number of what I think maybe authentic Native American baskets at an estate sale that also had Navajo weavings. I do not know really anything about how to determine if these are actually Native American but these two are very similar and the construction is interesting as it has a "wide" weave other SW baskets I seen are tighter. The colors especially the blue are quite lovely . Both are really well made and wanted an opinion from others. In any case and information would be greatly appreciated. Thanks much.
