In reply to Hendofan:
Route finding on Lagginhorn normal route is dead easy, but it is better to start from Weissmies hut rather than Hohsaas. Either way, walk across the ex glacier below the West face, up to the obvious col in the West ridge. There are many options in that blocky slope. Once you are on the ridge, just scramble up to the summit ice field. where there will be an obvious track.
I would not worry about rock fall, as long as you keep away from the face as you cross the dead glacier. However, especially late in the season (when the snow field at the top has become icy) there is some risk of slab avalanches following fresh snow fall. Better to wait a day or two until everything has settled, there have been some bad accidents in recent years, including one where an entire family died.
