Well I did some scouting this weekend. It is always good to learn new areas.

Sam's river Valley was good, hiked on both sides of the river. I didn't see any Elk but there was sign. Steep and thick in places, yes but there are huntable spots. A lot of the places to the river are straight down, but your are in the Olympic Mts.
One thing that I do know, you better know what your doing about packing meat out and keeping it from spoiling. It was an old road grade filled with about 100 wash outs from creeks and about 1000 man made dig outs so nature could reclaim the road. Rough to hike, Kick your a$$ to pack something out.
End result is if there are already people in there calling then it will be to crowded. The valley is big but the access it limited so everyone will be entering from the same place. Might be too crowded for me. Was already two groups camped on the main road, one at the end (start of the trailhead) and one about thousand yards before the end. Plus the Game Warden waiting for us back at the truck when we came out.
The Matheny Creek mainline was fixed. A new bridge was in and I got to explore that area. Found some really good areas. I can see where the Elk could get slaughter off the road in certain sections. Lots of Elk sign in the road.
Anyway the unit has potently so it could be an alternate location. I'm going to keep expanding my areas of searching next weekend though and look at the Quinault Ridge unit.
Thanks for all your help.
