1957 Map of Opalene Gulch

About this map

The Owyhee Mountains and the Snake River define the terrain of this mid-century Idaho survey, where water management is central to the landscape. To the north, the river winds around Fruit Island and Dilley Island near the settlement of Riverside, supporting a complex irrigation network including the South Canal, the Flat Low Line Canal, and various flumes and siphons. Local landmarks like the Opalene School and a Boy Scout Camp indicate the social hubs of this rural corridor during the late 1950s.
