The well-known Rhone glacier in the Alps is showing a spectacular and rapid retreat. A pro-glacial lake appeared in front of it in 2006. Called Rhonesee, it is gradually increasing in size and extent. Several photographs taken on June 28, 2018 show the retreat of the Rhone glacier and the extended features of the pro-glacial lake. It is considered that the glacier will continue to retreat in the future, and the extending Rhonesee could separate into large and small lakes.
