An alternate approach for this traverse to add more scrambling and difficulty. My approximate line in red from Brainerd Lake. Start at the notch in the ridge that runs north-south at the eastern most side on Middle Palisade Glacier to gain the ridge. The start is easy but quickly followed by some very exposed 4th class. The crux is a notch about half-way to the Palisade ridge (my guesstimate would be ~5.4, very exposed and loose). The rest of the ridge turns to 3rd class after this and then joins the Palisade ridge proper.
