The Spanish Peaks are made up of 1.6 billion year-old gneiss, making them the oldest peaks in the Madison Range, predating the rest of the range by 50-60 million years. Gallatin Peak, el. 11,015 ft., is the highest peak in the group.

Spanish Peaks-According to an oral history that Little Face, a Crow scout, told Lieut. James H. Bradley in 1876, these mountains were called Ol-ku-shu Ah-naht-si Ah-rah-sah-ti (Canyon where Spanish Stop). According to tribal legend the Crow found six Spanish trappers in the Gallatin Canyon around 1836. Stories of a rich gold mine found by these Spaniards helped fuel an abortive gold rush in the Gallatin Canyon around 1900. No mine and little gold have ever been found.
There was a small settlement called Spanish in the 1880s. It had a church that last ten years and a school that operated from 1883 until 1949.
