The path(s) from Stone Creek Rd through Stone Gap seems pretty indeterminate. It seems likely one route is under the existing road through the gap into Penn Roosevelt park. But examination in the SW corner of the gap shows clear RoW headed along the stream into the gap. Then it disappears 🙁 It’s unclear whether it has been wiped by flooding or whether it never continued into the gap. Was this a deadend spur, or was there actually a very big wye formed by two tracks through the gap?

It seems logical that route through Sand and/or Triester mountains would be in the gap at the zigzag in Crowfield Rd. But we’ve walked that gap, and gone up either side to the ends of Sand and Triester Mtns. No sign found! Is it just buried in the undergrowth, or what?

After considerable explorations, we can’t find the large horseshoe depicted by Kline in the vicinity of Faust Flat. Though it would seem it should pass through Smith Gap, no sign was found there, and the terrain seems very steep.

We have definite roadbed in the vicinity of Underwood Trail, but it disappears into brutal undergrowth before reaching Smith Gap.

Just where are the darn switchbacks into Bear Meadows? And looking at how rocky and steep Little Flat mountain is, why didn’t they just use the old tramroad route? Hmmm.

Precisely where was the sawmill at Linden Hall, and how did the railroad reach it? Examining Penn Pilot images and satellite views gives a few possible clues, but nothing definite. There is supposedly a book on Linden Hall’s history, which we need to find and peruse!
