The start of the #Mexican War with the United States in 1846 disrupted peace and by the time the US moved into the SW at the end of the war in 1848, the #Apaches posed an almost unsolvable problem

Western #Apaches lived primarily on western side of the Continental Divide, in the mountains of present day Arizona and Western New Mexico
Mount Graham (10,720ft elevation) is sacred land to the #Apaches
37.5 % of #Apaches had incomes at or below the poverty level as of 1989
