This is the Lago di Lei in Italy, an important source for hydro-electric power as it
flows into the young Rhine (Hinterrhein branch) in Switzerland's Canton Graubünden.
From an afternoon of auto-touring with my F-C friends Beatrice and Ruedi, who
introduced me to many special photo-enticing spots in their lovely Graubünden
(and neighboring Italy) that I certainly would not have discovered on my own.
From an Ektachrome transparency.
