Rottalgletscher, Glacier in the Bernese Alps, Lauterbrunnen, Switzerland

Rottalgletscher is an alpine ice field on the northern slopes of the Bernese Alps, spanning elevations between 2900 and 3000 meters. It sits within a landscape of towering rock faces rising more than 1000 meters that frame the glacier on multiple sides.

The Rottalhütte of the Swiss Alpine Club stands at 2755 m on the northern side of the Rottal, beside the glacier. In 2007 six Swiss Army recruits were climbing from the Rottalsattel to the Jungfrau through the Rottalcouloir when a snow slab broke loose; they fell 1000 m onto the Rottalgletscher and all died.

The Rottalhütte, a Swiss Alpine Club (SAC) hut at 2755 m on the northern Rottal side, is a base for climbers heading to the Jungfrau and surrounding peaks. It is reached on foot and provides simple shelter in a high-mountain setting.

The glacier lies in a cirque ringed by rock walls over 1000 metres high, below the Jungfrau, Rottalhorn, Louwihorn, Gletscherhorn and Äbni Flue, and flows west. The SAC's Rottalhütte stands at 2755 metres on the northern side, beside the ice. The approach is high alpine terrain; the 2007 avalanche in the Rottalcouloir, which killed six Swiss Army recruits, shows the hazard on the upper route.

The glacier's meltwater below 2500 m forms the Rottalbach, which feeds the Weisse Lütschine; from there the water runs via the Lütschine, the Aare and the Rhine to the North Sea. A tributary joins from the Gletscherjoch at 3762 m between Gletscherhorn and Äbni Flue, and part of the Stuefesteingletscher flows in from the foot of the Äbni Flue.
