The community of Simms serves as the northern anchor of this landscape, where the Fort Shaw Canal cuts through the plains north of the Crown Butte formation. This terrain is defined by dramatic volcanic features and mesas, including the prominent Square Butte and Birdtail Butte. The historical footprint of early transportation and settlement is evident at the Eagle Rock Stage Station (Site) and along the Mullan Road, a vital early route through the Montana Territory.
