About this map

Lake Sacajawea and the Snake River define the northwestern corner of this mid-1960s landscape, where the water's edge meets a complex network of transportation infrastructure. The territory is marked by the heavy influence of the railroad industry, featuring the Union Pacific and Northern Pacific lines as they navigate the shifting elevations near Eureka Flat. Evidence of older transit routes is preserved in the Old RR Grade and various Jeep Trails that crisscross the terrain.

Small settlements like Slater and Le Grow appear as quiet points along the rail corridors, supported by utilitarian landmarks such as a Water Tank and Storage Bin. The map also documents industrial and modern developments, from a Gravel Pit to a significant Pipeline stretching across the southern sections. This survey provides a clear view of the Walla Walla County countryside as it balanced mid-century infrastructure needs with the natural contours of the river basin.
