When we did Willow, we continued from the confluence with the Elk River to the bridge. On the Lower Elk there is one tree 3/4 across the river, roughly 1 mile up from the takeout bridge near Glen Eden (assuming that's a takeout). It was easily noticeable and passable in a kayak, and would probably be fine in a small raft.
Can any of the locals fill me in on the past diplomatic dealings with that Willow Creek man-made deathtrap? Why hasn't someone cut that thing out yet? Anyone have contact info for the landowner (to PM me, not publicly post)?
