Now our conclusions were strengthened by the appearance ofthe rocks themselves, which showed a clear contrast between the light-coloiued sedimentary and calcareous formations, and the black and.

This alternation of material in the upperBaltoro is clearly displayed in Sellas panorama M, taken from thecrest between the Vigne and the upper Baltoro. The centre showsthe black stripe formed by the right-hand moraine of the Vigne andthe left-hand of the Baltoro. It is all composed of granites and quartzesfrom the Bride Peak chain. Next, on the right, is a second band(coming from the right-hand lower corner of the panorama). Itssource is the confluence of the eastern glaciers of Bride Peak.
