FYI, I talked to the Forest Service on Saturday and I was told that the Mt. Clinton trail is slated for major work once they finish with the Rocky Branch Trail.
Yesterday, I took a stab at it from the Dry River Trail. The crossing of the Dry River was a piece of cake because of the low water levels. From there, a line of cairns leads across the river. Do not duck into the woods here, as I did on my ascent, instead, follow the line of cairns slightly upstream. Soon, a length of orange flagging tape directs you to where the trail enters the woods. From here, the trail is quite obvious underfoot. The orange flagging tape serves as a reminder that you are on the trail, but it's not really necessary as you can tell the treadway characteristics are quite intact. This lower section is overgrown with hobblebush. I had my clippers with me because I had been doing trailwork on Webster Cliff Trail earlier. I did some judicious pruning, but it soon became obvious that no amount of clipping that I could do in an afternoon was going to make a dent in what needed to be done. I continued to follow the trail and the flagging, thinking that things were going much more smoothly than I anticipated. At about 0.5, I reached a large blowdown and the trail underfoot disappeared. I suspect the blowdown falls on the treadway, but it was quite jumbled in this area. The flagging continued, and I followed that for another 0.1 of bushwhack, not at all confident that whoever had flagged it knew the trail at this point. I could hear the brook nearby, but the flagged route seemed to lead more to the left of the water. At this point, the hour was getting late and I had a cold beer and a swimming hole calling to me. Perhaps I will try to descend it next time. I think, as Becca M points out, that may be the lesser of two evils. In the meantime, if anyone tries descending soon, rest assured that when you come to the orange flagging tape at the bottom of the trail, you will have an easy time of following the trail to the river.
