Wetlands used to dominate the Willamette Valley, but only remnants of the wetlands remain. This scene is in a portion of the wetlands west of Eugene. The tall yellow grasses are beautiful.
From the - http://www.eugene-or.gov/644/Wetlands - website:
"Historically, much of the Willamette Valley was dominated by this plant community. Most of it has been lost, making the remaining areas within Eugene’s Park and Open Space system even more valuable. These areas not only provide homes to a wide diversity of animals and plants, but they also provide important functions for our community such as cleaning our stormwater, helping reduce flooding impacts, and providing beautiful landscapes for recreation, education, research, and solace."
