I *think* the "pinch point" is not in Bill's series of photos. It's really easy to miss it when you are hiking the ROW. The original ROW slid away, but when the area was logged, they just cut more of the embankment aside. Then all the trees grew up around it. So it looks like the ROW, but it isn't. The only give-away are the divots left in the ground where the ties rotted away.
My understanding is that we are going to lay the track here on this slightly modified alignment, rather than deal with repairing another slide (which is in a more environmentally sensitive area due to its proximity to the brook.)
