Carlton Peak is a summit in the Sawtooth Mountains in southern Tofte Township, Cook County, in northeastern Minnesota in the United States. In 1848 Reuben B. Carlton of Fond du Lac, Minnesota ascended the peak with Col. Charles Whittlesey, who was participating in a geological survey expedition. In appreciation, Whittlesey named the mountain in Carlton's honor.[1] Carlton Peak (south and east side at least) is now a Day Use area of Temperance River State Park and requires a valid Minnesota State Park sticker per sign on road south side of peak.
