Walkerville, a historic district adjacent to Butte, was named for the Walker Brothers of Salt Lake City, Utah, who owned and operated the Alice Mine at Walkerville. Walkerville was home to some of the earliest mining sites in the area. Copper and silver were most commonly mined. Present day Old Lexington Stamp Mill and Gardens marks the site of Butte's first smelter. The major features remaining at the Lexington include the steel headframe over the shaft, the hoist house, and a steel idler tower.
