"ebbinghaus", using the map for REF: I followed parallel on the left of stream branch split of Ermine Brook and continued a straight line up to the shoulder ridge SE of the summit, mentioned earlier, then a left curling turn up to the summit area. From the map those white narrow areas would probably be open cliff faces, something I was not equipped to deal with. The road/horse trail to Ermine Brook is kind of rough (rocky) in spots. You have to be very careful and walk the bike up some inclines too. I figured my bushwhack route was about 2 mi. each way; your suggestion (if I'm following it correctly) appears to add another mile or so.
