Navajo and Hopi tribes campaign to remain on Black Mesa lands and protect it from coal mining, United States, 1993-1996
The land on the Big Mountain reservation has been disputed by the U.S. Government and the Navajo and Hopi tribes since 1882. This area in Black Mesa, Arizona, which was extremely rich in sulfur coal deposit, attracted mining companies and the government due to the potential profit. Mining began on the Navajo and Hopi land and started to increase greatly by the 1970s. Congress signed a relocation act in 1974, which would allow one company, Peabody Coal, to mine this area uninhibited. The reservation lands of Black Mesa were then to be used as strip mining sites for private U.S.
