Grasshopper Valley cuts a prominent diagonal through this Montana landscape, following the course of Grasshopper Creek as it winds past the historic grounds of Bannack State Park. This region, documented during a late-1990s revision, shows a rugged terrain defined by significant mining and industrial activity, evidenced by Tailings, multiple Prospects, and a Claypit near Dyce Creek. Local history and genealogy are centered on the Bannack Cem and nearby Campgrounds, situated where the valley narrows. The hydrology of the area is complex, with numerous tributaries such as Cottonwood Creek, Taylor Creek, and Sagebrush Creek feeding the main drainage. To the north, Mill Point stands as a distinctive landmark above the confluence of Swamp Creek and Hayes Creek, illustrating the transition from open valley floor to the more complex topography of the Beaverhead region.
