deemed an experimental Indian reservation that failed because it became too expensive, there were too many people to feed, and they were continuously raided by other native tribes. Consequently, in 1868, the Navajo were allowed to return to their homeland after signing the Treaty of Bosque Redondo. The treaty officially established the "Navajo Indian Reservation" in Northern Arizona. The term reservation is one that creates territorialities or claims on places. This treaty gave them the right to the land and semi-autonomous governance of it. The Hopi reservation, on the other hand, was created through an executive order by President Arthur in 1882. A few years after the two reservations were established, the Dawes Allotment Act was passed under which communal tribal land was divvied up and allocated to each household in an attempt to enforce European-American farming styles where each family owns and works their own plot of land. This was a further act of enclosure by the U.S. government. Each family received 640 acres or less and the remaining land was deemed "surplus" because it was more than the tribes needed. This "surplus" land was then made available for purchase by American citizens. The land designated to the Navajo and Hopi reservation was originally considered barren and unproductive by white settlers until 1921 when prospectors scoured the land for oil. The mining companies pressured the U.S. government to set up Native American councils on the reservations so that they could agree to contracts, specifically leases, in the name of the tribe. During World War II, uranium was mined on the Diné and Hopi reservations. The dangers of radiation exposure were not adequately explained to the native people, who made up almost all the workforce of these mines, and lived in their immediate adjacency. As a result, some residents who lived near the uranium projects used the quarried rock from the mines to build their houses, these materials were radioactive and had detrimental health effects on the residents, including increased rates of kidney failure and cancer. During extraction some native children would play in large water pools which were heavily contaminated with uranium created by mining activities. The companies also failed to properly dispose of the radioactive waste which did and will continue to pollute the environment, including the natives' water sources. Many years later, these same men who worked the mines died from lung cancer, and their families received
