The poster by Daniel E. Coe shows the life-like historical flows of the Willamette River in Oregon.
This lidar-derived digital elevation model of the Willamette River displays a 50-foot elevation range, from low elevations (displayed in white) fading to higher elevations (displayed in dark blue). This visually replaces the relatively flat landscape of the valley floor with vivid historical channels, showing the dynamic movements the river has made in recent millennia. This segment of the Willamette River flows past Albany near the bottom of the image northward to the communities of Monmouth and Independence at the top. Near the center, the Luckiamute River flows into the Willamette from the left, and the Santiam River flows in from the right.

The Willamette River map is a stunner!
Fabulous image. An important thing to remember about the Willamette River and Valley is that it was shaped by the great ice age floods of Glacial Lake Missoula when the flood waters backed up as they encountered the Coast Range mountains.
