Pollux

Pollux is a mountain in the Pennine Alps on the border between Valais, Switzerland and the Aosta Valley in Italy. It is the lower of a pair of twin peaks, the other being Castor, named after the Gemini twins of Roman mythology. Pollux' peak is at an elevation of 4,092 m. It is separated from Castor by a pass at 3,847 m, named Passo di Verra in Italian, Col de Verra in French and Zwillingsjoch in German.

The first ascent was by Jules Jacot from Geneva with guides Josef-Marie Perren and Peter Taugwalder on August 1 1864. Their route was via the Schwarztor, a pass first crossed by John Ball and Gabriel Zumtaugwald in 1845. The impressive north ridge was first climbed by Captain John Percy Farrar and Wylie Lloyd with guide Josef Pollinger of St. Niklaus in the canton Valais on 18 August 1893.
