Mackenzie OlivoUnderscore Native NewsSince March 2025, some Native cultural artifacts and sacred sites have been left vulnerable after Congress rescinded reporting requirements for development proposals on the Outer Continental Shelf. Thompson-Upton’s traditional lands along the coast of Northern California would be impacted by the development of the Outer Continental Shelf (OCS). Some Native nations, like the Confederated Tribes of Grand Ronde, plan to assert treaty rights to protect impacted lands. Grand Ronde says their 2023 treaty is the supreme law of the land which supersedes any law that conflicts with tribal resources. According to Grand Ronde Deputy Press Secretary, Sara Thompson, Grand Ronde recognizes resource protection laws as they existed in a 2023 signed treaty.
