About this map

The Columbia River forms the defining boundary on this 1993 map, separating Washington and Oregon while carving out a complex network of waterways and islands known as Lake Umatilla. This stretch of the river is dominated by the Blalock Islands National Wildlife Refuge, featuring a chain of landforms such as Telegraph Island, Sand Island, and Little Blalock Island. The landscape is bisected by the North Channel and South Channel, illustrating the dynamic hydrology of the Columbia before it passes the southern slopes of Paterson Ridge.

Away from the water, the terrain rises sharply into the arid uplands of Canoe Ridge, where drainage is marked by the winding paths of Glade Creek and East Glade Branch Creek. Human activity is sparse but visible through a prominent Pipeline and a remote Landing Strip, suggesting an era of industrial utility and energy transit. For local historians, the map preserves the exact positions of family-named landmarks like Whitcomb Island and the isolated Substa near the eastern margin.
