Final answer:
The reservation near Grand Coulee is the Grand Ronde Reservation. Life there was challenging due to poverty and inconsistent federal aid, as reservations were considered federal lands and Native nation's sovereignty depended on federal governance.
Step-by-step explanation:
The Native American reservation near Grand Coulee was known as the Grand Ronde Reservation in Oregon. While the reservation system aimed to establish peace and provide a means for Native Americans to live, life on reservations like Grand Ronde was difficult, with many indigenous peoples living in poverty and facing challenges related to food scarcity, health care shortages, and other logistic issues associated with the distribution of federal aid. The patriarchal rulings of the Marshall court trilogy declared that reservations were federal lands and that the sovereignty of Native nations within the United States was dependent on the federal government.
