About this map

The Snake River carves a deep, winding path through the high desert of southwest Idaho, defining the boundary between Ada and Owyhee counties. This post-war survey details a landscape where historic overland travel meets early 20th-century irrigation engineering. The Emigrant Trail is clearly traced as it skirts the southern bluffs above the river, passing near landmarks like Jackass Butte and Black Butte.

Agricultural life on the Chattin Flats is sustained by an intricate network of water management, including the Grand View Mutual Irrigation Canal, the High Line Canal, and even specialized structures like a Flume and Siphon. Local infrastructure is anchored by the Brooks Ranch and the Birch Creek Sch, while natural drainage features such as Rabbit Creek and McKeeth Wash illustrate the complex desert topography surrounding the river valley.
