The Snake River carves a complex boundary between Oregon and Idaho on this 2014 survey, defining a landscape dominated by riparian islands and an extensive irrigation network. Large landmasses like Morton Island, McPhersons Island, and Perrin Island sit within the river's channel, while the surrounding plains are etched with vital waterways including the Farmers Cooperative Canal, A Line Canal, and Noble Canal. This area marks a significant junction of three counties—Malheur, Payette, and Canyon—centered around the communities of Nyssa and Fruitland.
