1800m. Swindin says, "A safer way up the NE Face (and with more mixed climbing) than that Lauper route in that it is not so exposed to avalances..." I found it to be relatively free from rock fall due to it being a buttress. That is not to say that there is not a lot of loose rock on it that you can kick down on your belayer. Like many Eiger routes now it is probably safer to climb it in the colder months. I tried it in July and there were running waterfalls on the route.
