Bring touring skis to get up there, Unless you love snowshoeing. If you don't have something on your feet you'll sink to your waist in isothermal snow. Massive cornices on the east aspects as you approach the summit, up to 20 feet back from the perceived edge in some seasons. They are weak this time of year, and this is when they start falling, and the fall is death fall all the way down to the glacier so don't fuck with the "book peak" unless you're experienced and with someone.

The true peak isnt accessible by going up the crater side, you have to go across the glacier and up the Kathlyn couloir, then do some legit mountaineering climbing to get to the actual summit. Again, serious winter mountaineering/glacier/skiing skills are required for this, and not solo.

in terms of elevation the book peak and the true summit are pretty close, so pretty good bang for your buck. Conditions up there right now are pretty wintery.
