A photography exhibit by a University of Colorado at Boulder professor featuring landscapes altered by human construction in the West will be on public display through the month of April at Boulder's National Center for Atmospheric Research. Titled "The House, the Road, and the Valley," the exhibit was created to show how modern culture has changed the landscape in both harmonious and discordant ways, said Tad Pfeffer, associate director of the Institute of Arctic and Alpine Research. The show contains 21 photos of the changing West, many of them on Colorado's Front Range.
