Farthest source of the Columbia River is Lake Columbia, in BC near the source of the Kootenai River. Through geologic time, that drainage switches between Columbia and Kootenai depending on glacier positioning!
I'm slowly collecting sources of major Oregon rivers. The source of the John Day River (my favorite) is in the study area I did my Master's in.
