Established February 6, 1917 with its county seat at Arco. It was named for the buttes that rise from the Snake River plain and served as landmarks to trappers and pioneers who traveled through the area. The first white men in the region were thought to be Donald Mackenzie and his Northwest Fur Company trappers in 1818.
