2020 Map of Lewiston Orchards South

About this map

Lewiston and the suburban layout of Lewiston Orchards occupy the northern plateau of this Idaho-Washington borderlands survey. The landscape drops sharply from the residential grids of Grelle Avenue and Powers Avenue into a series of dramatic drainages carved into the basalt. Tammany Creek winds below Tammany Ridge, while further south, the terrain becomes deeply dissected by Tenmile Canyon, Short Canyon, and Homestead Canyon. This rugged topography defines the transition from the city's orchard-district roots to the expansive grazing lands of Big Bench. Along the southwestern edge, the Snake River marks the state boundary, featuring Ackerman Bar and the steep slopes of Weissenfels Ridge. The map documents the persistent agricultural character of the region, anchored by landmarks like the Tammany Cemetery and the Lewis and Clark Memorial Gardens.
