TheUmatilla National Forest, in theBlue Mountains of northeastOregon and southeastWashington, covers an area of 1.4 million acres (5,700 km2). In descending order of land area the forest is located in parts ofUmatilla,Grant,Columbia,Morrow,Wallowa,Union,Garfield,Asotin,Wheeler, andWalla Walla counties. (Columbia, Garfield, Asotin, and Walla Walla counties are in Washington, while the rest are in Oregon.) More than three-quarters of the forest lies in the state of Oregon.[4] Forest headquarters are located inPendleton, Oregon. There are localranger district offices inHeppner andUkiah in Oregon, and inPomeroy andWalla Walla in Washington.[5]

The Umatilla National Forest takes its name from theUmatilla Indian word meaning "water rippling over sand." ExplorersLewis and Clark passed through the area in 1805 on theColumbia River, andMarcus and Narcissa Whitman passed through in 1836 to establish a mission at Wailatpu nearWalla Walla, Washington. Thousands of emigrants later followed theOregon Trail west, and many remained in the Blue Mountain region. Discovery of gold in Oregon in 1851 led to the settlement of the North Fork John Day River area. More than $10 million in gold and silver were mined, and remnants of the era are still visible in the National Forest. Some claims are still being mined.[6]
