Yes Mike Dark Canyon put in.
So Anthracite is fairly clean overall. If you put in all the way to the end of Dark Canyon campground at the Trailhead you will immediately be facing some strainers in very fast moving water that all go without getting out of the boat but its definitely heads up. You can avoid that 1/4 mi section by putting in closer to the bridge & may as well really cause some of that stuff may shift after this post & be more of an issue. Rest of the run is reasonable but there is wood in there that may shift so be safe.
