2020 Map of Slater

About this map

The Snake River carves through the northwestern corner of this territory, where its waters form Lake Sacajawea behind the downstream dam system. This Walla Walla County landscape is defined by the broad, high-elevation expanse of Eureka Flat and a network of rural roads that follow the section lines of the Public Land Survey System. The small settlements of Slater and Le Grow sit within this agricultural and arid terrain, connected by thoroughfares such as Ice Harbor Dr and Agate Rd. The topography is marked by numerous draws and coulees, typical of the regional geography shaped by the river's drainage patterns. This modern survey reflects the enduring rural character of the area, where large-scale farming and water management are the primary drivers of the local economy and land use.
