N. Horn/Potato Nubble
I was there last Fall..... I approached on the Redington Rd (from Rt 16). Just before the closed gate to the miliary preserve is an access rd to a gravel pit on the south side, where I parked. A well-travelled gravel rd leaves the pit (shown on the Delorme map connecting with the Mountain Rd to Saddleback). I found the abandonded logging roads (on the Topozone maps that Dennis posted) relatively easy to follow, and the climb to the N Horn was mostly open. The ridge over to the Nubble, however,after a promising start, was a "bear" (or some other "b"-word). To avoid the military preserve and the nasty blowdown, I fell off to the west side of the ridge. The south end of Potato Nubble looked rather "cliffy", so I'd recommend climbing it from the western side, too. The whole area is laced with herd and skidder paths, some easier travelling than others. As other reponders have indicated, this is a tougher than average loop, and adding in SW Black Nubble would have been more than I would have wanted to do! The summit register on the N Horn was in hundreds of pieces on the ground and the register itself was completely soaked with the entries all obliterated. The Nubble "jar" was still attached to a tree, but the lid was gone and, again, the log book completely destroyed by water.
