About this map

The Missouri River winds through the northwest corner of this landscape, its path defined by the broad curves of Tintinger Slough and the nearby Antelope Flat. This terrain is characterized by a sophisticated network of irrigation and water management, most notably the Chestnut Valley Canal and the Dana-Cameron Ranch Dam, which redirect the flow from natural drainages like Sheep Creek and Willow Creek to support the local ranching economy.

Genealogists and local historians can locate the Chestnut Valley Cemetery situated in the northern reaches of the quadrangle. The topography rises toward the south, dominated by the prominent Harris Mountain and the distinctive geological formation known as Rocky Reef. The presence of numerous named drainages, such as Harris Creek, Allen Creek, and Cherry Coulee, reveals the complex hydrology that has shaped the settlement patterns and agricultural development of this Montana valley.
