About this map

The confluence area of the Snake River and Boise River defines this western Idaho landscape, where a sophisticated network of irrigation sustains the agricultural communities of Wilder, Homedale, and Roswell. The terrain is marked by the transition from river bottomlands at Goat Island and Gravelly Point to the elevated benches of Arena Valley. An intricate system of water management is visible through features like the Riverside Canal, Fargo High Line Canal, and dozens of smaller laterals such as the Plowhead Lateral and Watts Lateral.

Genealogists and local historians can locate several burial grounds serving these rural townships, including Roswell Cem, Wilder Cem, and Fargo Cem. The map also traces the winding course of the Snake River as it forms the boundary between Canyon and Owyhee Counties, flanked by landmarks like Mammen Gulch and Christian Gulch. These features illustrate the early 21st-century character of a region deeply tied to its river-and-canal economy.
