Mount Graham

Mount Graham Dził Nchaa Sí'an - ′Big Seated Mountain′) is a mountain in Graham County, Arizona, United States, approximately 70 miles northeast of Tucson. The mountain reaches 10,724 feet in height. It is the highest elevation in Graham County, Coronado National Forest and the Pinaleño Mountains It is also the southernmost peak and land area in the continental United States above 10,000 feet . As the name "Mount Graham" is often used by locals to refer to the entire mountain range, the peak itself is frequently referred to as "High Peak". It is twentieth of the 57 ultra prominent peaks of the lower 48 states, and the first of the five in Arizona.
Mount Graham summits are headwaters for numerous perennial streams that tumble through five major botanical zones. Located between the southern Rocky Mountains and Mexico's Sierra Madre Occidental, and biologically isolated for millennia, the higher elevations have provided refuge for relict populations of plants and animals with adaptive strategies rooted in Pleistocene ice age environmental conditions. Of particular note are stands of the oldest conifer trees in the U.S. Southwest and associated habitats for threatened and endangered species, especially the Mount Graham Red Squirrel.
