About this map

Downey sits as the central hub of this eastern Idaho landscape, where the valley floor meets the rising peaks of the Portneuf Range. The map documents a complex irrigation and drainage network vital to the region's agricultural character, including the Portneuf Marsh Valley Canal and Marsh Cr. Local heritage is anchored by several sites of significance to genealogists, such as Downey Cem, Marsh Valley Cem, and the Grant Ward Cem.

South of town, the terrain transitions into the area around Zenda and the recreationally important Downata Hot Springs. The mapping detail captures the intersection of rural life and transit, from the Downey/Hyde Memorial Airport to the deep incisions of North Fork Reed Canyon. These features illustrate a community defined by its water resources and the steep topography of the surrounding basins, maintaining a clear record of the area's infrastructure and land use in the late 2010s.
