Greg and i are currently out in the Oberland. On the 16th June we walked into the Rottal Hutte. On the 17th we made a very early start and climbed the Roti Flue on the North Face of the Abeniflue (TD). We had to make a detour downwards to approach the route as a large serac now threatens the normal approach (and collapsed during the night). This serac has appeared since the last guidebook was published and therefore not mentioned.
We stayed overnight at the Hollandia Hutte and then returned to the valley the next day. Photos can be seen on Greg Boswells blog. Currently it is raining and we are recovering in the valley.
