The evolution of the Columbia River drainage system on the Columbia Plateau of Washington in the last 17 My reflects the geologic history of the plateau. We have updated an interpretation of the evolution of the Columbia River system and defined the geomorphic and structural features that have controlled the position of ancestral streams. The sequence of geologic events and the resulting drainage system for various time intervals in the last 17 My are summarized below. 121 refs., 14 figs.
