The very start is often thin, but there are various ways of reaching the ledge of the main flow, so whatever looks doable is usually the best approach. The rest of the climb follows obvious ice with WI3 and WI4 options. A deciduous tree (I don't remember what kind, but might be beech) is the belay and rappel station for the final pitch. Two 60m ropes are handy for the descent. I have only done this climb once, so if anyone has better beta, please mention it. Great exposure and several route options.
Ice screws. Rap anchor on a tree after the last pitch and another, similar anchor on the large, snowy ledge below it.
