This process can be seen today in the eastern Grand Canyon where Seventyfive Mile Canyon is eroding away the saddle at its head. Very soon, geologically speaking, Seventyfive Mile Canyon will capture the drainage of Tanner Canyon, which is only a few dozen yards from the saddle, and divert upper Tanner Canyon into Seventyfile mile Canyon.
