Did that same hike many years ago, must been in the seventies (before 1980) in July. They were still summer-skiing and whole most of the path from the Felskinn mountain station (if I remember the name correctly) to Britania hutte was over a glacier covered with snow. Also the way down from Britania was over a snow covered glacier. We were knee-high in the snow in the afternoon. Very little remains from those glaciers.

Hopefully going there in June. Wish I'd gone 30 or 40 years ago...
