Yeah was similar conditions when I last did it in 2019 as a Momyer loop. Some rockfall up on higher switchbacks and definitely some buckthorn/whitethorn bushwacking on some overgrown switchbacks.
In general only one part of one switchback had an obstruction – I think large tree fall and/or maybe rocks – where we had to go straight down to the next one.
I recommend if you have a track for the trace trail you use it to ensure you are on the route. It’s a beautiful trail have fun!
