1962 Map of Hat Rock

About this map

Lake Wallula dominates the center of this survey, marking the flooded landscape created behind the McNary Dam along the Columbia River. The state boundary between Washington and Oregon runs through the center of the lake, separating Benton and Umatilla counties. The map captures a moment of infrastructure development, showing the Spokane Portland and Seattle Railroad hugging the northern shore while the Union Pacific Railroad serves the southern side. On the Oregon shore, Hat Rock State Park and the distinctive Hat Rock formation stand near the water's edge, while the inland areas show a transition to agriculture and industry with various gravel pits and a series of rural roads like West Locust Road and East Progress Road. Conservation efforts are also visible at the Cold Springs National Wildlife Refuge in the southeast.
