2023 Map of Slater

About this map

Lake Sacajawea anchors the northwestern corner of this landscape in Walla Walla County, where the terrain transitions into the broad expanse of Eureka Flat. The area is defined by a series of north-south ridges and draws, with the small settlements of Slater and Le Grow serving as central points in a remote agricultural and utility network. A system of gravel and paved roads, including Slater Rd and Agate Rd, connects these outposts across the high ground. The map reflects a modern view of the region's land management and irrigation potential, with Ice Harbor Dr tracing the higher elevations near the water. This 2023 survey provides a clear look at the contemporary infrastructure and topographic contours that dictate movement through this part of eastern Washington.
