The White River Bridge on Oregon Route 35, east of Mount Hood, after the debris flow events of early November 2006. Note the blue-jacketed person standing in the channel near the center of the bridge span. The debris deposit is roughly 12-18 ft high on the upslope side of the bridge. Debris completely filled the channel and overtopped the bridge deck. Route 35 was re-opened December 9, 2006. Read more about debris flows in the White River Valley in the newest issue of Oregon Geology.  (Photo by William J. Burns, DOGAMI. ).
