The Navajo people, whom live in the Southwest on the borders of Arizona and New Mexico and have by land area the largest reservation in the US are Athabascan -- aka, Pacific Northwestern. They showed up in that area as conquerors not long before the Spanish showed up. Some of the other tribes and native people still harbor resentment that the borders got drawn when they did, because they were working on repelling them. To the point that as a kid, when we'd have field trips to various natives monuments or communities, different native kids from different tribes would not go to depending upon which tribe / monument we were visiting.

And they very much did believe in the thought of owning land; they just didn't have property deeds written out, and have communal thoughts on more things, but still had the concept of private residences and private belongings, and private separate spaces to exist in. There's still a bit of the noble savage myth going on and circulating around a lot of this (the various tribes and people that compromise the native americans were really fairly typical stone age societies).
