The first ascent of the mountain to the
Schneekuppe was by F. T. Bircham with guides Peter Jenny and Alexander Fleury on 31 August 1863. The highest point of the mountain was reached two years later by
A. W. Moore and
Horace Walker with guide
Jakob Anderegg on 28 June 1865. The first guideless ascent was made on 7 August 1882 by
Charles Pilkington, his brother Lawrence and Eustace Hulton. Piz Roseg is separated from the neighbouring
Piz Scerscen by the
Porta da Roseg (3,518 m), also called the
Güssfeldtsattel. The Swiss side of this col – a steep ice slope of up to 70° – was first climbed by
Paul Güssfeldt, with guides Hans Grass, Peter Jenny and Caspar Capat on 13 September 1872. Grass and Capat had spent the previous day cutting steps up the first two-fifths of the route. The following day they added at least another 450 steps on the first ascent. The 700-metre north-east face of Piz Roseg was first climbed by
Christian Klucker and L. Norman-Neruda on 16 July 1890; the face – with a notable
serac band halfway up – sports a number of difficult routes. Klucker, together with M. Barberia, also made the first traverse from the Italian side of the
Porta da Roseg on 21 June 1898. ==See also==
