A recent legislative agreement to dismantle four controversial dams on California’s and Oregon’s mighty Klamath River has been described as the largest river restoration effort in all of U.S. history.

This video memorializes these imperiled, unexpectedly grand, and undeniably problematic monuments in their dramatic Cascade Range environment. (© 2010, running time: 8 minutes.)
