As part of not-quite PTSD, I remember every step of Chimney Notch about 5 years ago on a dry, warm day with no wind...
Climbed up the Dudley Trail, was more tired than I thought I'd be early on. Looked over from Pamola and thought "No way I can do this, no way, no way. Nonononono". Everyone else in the group, including some 30 years older, went at it without a peep. Thought to self: "OK, guess I have no real choice". The first 20 yards were OK. The next 100 yards were unbelievably steep and exposed, but there were really only about 10 big down-steps where people were helping each other out: "Step here, here, here and here." 2 or 3, I could not see my feet or where to put them. No big deal physically, really, just that you had to have your feet and your balance exactly right, and not fall. I never fall anyway, but this time I had to REALLY not fall.
At the bottom of the Chimney, another 100 yards very steep up. This was OK, as steep up is no big deal. Exposed, yes, but handholds were fine and straightforward.
Rest of the KE was just a deliberate, slowish rockhop with hands needed now and then.
