Climbing
First ascent	5 August 1869, by Viktor Haller, Joseph Maria Trösch and Angelo Boffa [2]

The massif of Piz Rotondo separates the valleys of the upper Rhone (Valais) and upper Ticino. About two kilometres north-east lies the Witenwasserenstock, which is the watershed between the basins of the Rhone, Po and Rhine.

On the north side lies a relatively large glacier named Gerengletscher, which extends to the ridge of the Witenwasserenstock. On the south side, at Passo di Rotondo, lies a smaller glacier named Ghiacciaio del Pizzo Rotondo.

The first ascent by Viktor Haller and his guides on August 5, 1869, started from Bedretto in Ticino over the east face and the (by now nearly gone) Pesciora glacier. Only four days later, the second ascent took place, this time from the other site. F. Schläpfer and his guides Rudolf Elmer and Johann Kreuzer, started from Oberwald, and made the first ascent of the north summit via the long Geren valley and the Geren glacier. Only Elmer and Kreuzer traversed to the somewhat higher southern summit.^[2]
