You can hang the history of the Willamette River on your wall in a poster that combines art and technology.

The Oregon Department of Geology and Mineral Industries released a full-color poster showing historical channels of the Willamette River.

A laser-mapping technology called lidar allows for detailed and accurate mapping of the earth's surface.

The digital elevation model of the river shows a 50-foot elevation range, from low elevations displayed in white to higher elevations in dark blue.

The segment of the river featured in the poster flows past Albany near the bottom and goes north to the communities of Monmouth and Independence at the top. Near the center, the Luckiamute River flows into the Willamette from the left, while the Santiam River comes from the right.

This imagery was featured in the North American Cartographic Information Society's first Atlas of Design. The image was also highlighted in an American Scientist article that discussed the interplay of art and technology in map-making.

The poster is 17" by 38" and costs $15. For more information, go to www.naturenw.org.
