2020 Map of Ayer

About this map

The Snake River carves a deep valley through the high plateau of the Inland Empire, serving as the primary geographic corridor and boundary between Franklin and Walla Walla counties. The small settlement of Ayer and the nearby locality of Rifton occupy the southern banks, where the terrain transitions from the steep walls of Fields Gulch to the broader river terraces. This 2020 survey illustrates a landscape defined by the impounded waters of Lake Herbert G West, reflecting the modern regulated state of the river system. Transportation through this sparsely populated region is limited to a few arterial routes like Ayer Rd and Lyons Ferry Rd, which navigate the dramatic elevation changes between the riverbanks and the surrounding agricultural uplands. Smaller features such as Chew and Joe Barker Rd provide localized points of reference within the expansive canyon topography.
