Postscript to the West Horn Peak Post
Just a quick update regarding the high point on West Horn Peak: I was up there this past weekend, and after thrashing through and over all the little knobs, I concluded that the true high point was near the spur path for the viewpoint (it's right near the junction of the AT and the spur path). I found another point about a hundred feet to the west that seemed to be another contender (and it was about 15-20 yards off the AT [although this is just approximate, since it can be difficult to judge distances while one is fighting through scrub]), however, the elevation lost in walking over to it wasn't quite made up for by ascending the bump. Unfortunately, I didn't have an altimeter with me to determine definitively which bump was the highest, and the readings I was getting from my GPS weren't consistent enough to even determine through relativity which was the highest bump (it would give one elevation, then I would take two steps to the right and it would give another reading that was forty feet higher, so in those conditions I wasn't even able to go with whichever bump received the highest elevation reading).
So anyway, after much study of the area, I went with the bump by the view point (it's the second signed outlook west of where the AT meets the Horns Pond Trail, and the first east of where the AT reaches the top of the Bigelow Ridge). I put up a register jar, and when I was leaving the site I felt kind of silly, because only then did I realize that the spot was within sight of the AT. Since it seemed the transparent jar was easy to miss, I marked the tree trunk with yellow caution tape. I just hope doing so wasn't overdoing it. Also, if anyone finds that the canister was placed on the wrong bump, be sure to have a screw driver with you for moving it to the correct one (and definitely post here that you've done so). Suffice to say (to answer my own original question), the AT doesn't pass over the true high point of West Horn Peak, since there is a noticeable, if not very dramatic, elevation rise to the south of the trail.
