Believe you me, I even visited that region once, so I am familiar with the Eiger (as well as the Mönch and Jungfrau) peaks, as well as the Aletsch glacier, but I had never heard of the Massa river before (probably because it only has that name for 7 km before it flows into the Rhône). So I still think the naming is unfortunate...
