Abstract: This dissertation argues that Indigenous peoples use national parks both spatially andimaginatively to maintain a continuum of place-based community and innovate tribal expression.It thus restores the national park as a site crucial for exploring the intersections betweenIndigenous and modernist studies. The Indigenous studies aspect inheres in how the parks wereterritorialized by the U.S. government but Native Americans resided in them conditionally undera rubric of Western ethnography and primitivism. Tribal interventions to stay on their ancestrallands despite colonial enclosure expand Indigenous studies conversations about Native peoples’self-determination and outdoor tourism. The modernist component is intrinsic inasmuch as theirself-determining efforts were creative uses of the epistemological, technological, and aestheticchanges that national parks bring to their homelands. Within and/or with the park, tribalcommunities innovate an Indigenous modernism that is part traditional or stemming from longheld practices, part adaptation based on settler influence. By highlighting the respective logicsand philosophies undergirding their conglomerate (hybrid settler and Indigenous) houses,clothing, baskets, and poetry, we see that the national park operates as a zone of density wheresettler and Indigenous epistemologies and praxes of nation, time, place, and health are enacted,challenged, and appropriated. Tracing this density permits grasping Indigenous, relational modesof conceptualization and praxis; aesthetic, imaginative elements of Indigenous agency in U.S.colonial history; and how modernism existed outside of the metropole, at the confluence of theAmerican West and Indian Country particularly.
