1946 Map of Mouth of Bruneau

About this map

Snake River and Bruneau River converge in this high-desert canyon landscape, where the historic Emigrant Trail traverses the benchlands south of the water. The survey, compiled from 1946 aerial photography, captures the intersection of early Western migration routes and mid-century ranching life. Key landmarks such as Halls Ferry and the Roy Johnson Ranch indicate the importance of river crossings and irrigation in this arid environment. The presence of Petroglyphs near the mouth of the Bruneau suggests a deep human history in these canyons, while features like the Gaging Sta and an Artesian Well reflect the ongoing efforts to manage water resources in the Little Valley region. Below the high bluffs, the river drops through Ninefoot Rapids, a notable obstacle for early navigation along the Elmore and Owyhee county border.
