Lower Grindelwald Glacier

The Lower Grindelwald Glacier (Unterer Grindelwaldgletscher) is a Glacier in the Swiss Bernese Alps, situated to the south-east of Grindelwald. It starts below the Agassizhorn and the Strahlegghörner and is connected with the Finsteraar Glacier via the Finsteraarjoch (3390 m).

The Lower Grindelwald Glacier yet has a major tributary, the Ischmeer (Swiss German for Ice Sea, formerly known as Grindelwald-Fiescher Glacier, Grindelwald-Fieschergletscher), which is the glacier overlooked by the Jungfrau Railway's Eismeer railway station.

The Lower Grindelwald Glacier was about 8.3 km long and covered an area of 20.8 km2 in 1973. The glacier has significantly shrunk since, having a length of just 6.2 km in 2015, with most of the retreat (1.9 km) happening since 2007.

In the middle of the 19th century it clearly reached into the valley of Grindelwald as far as Mettenberg at an altitude of 983 m, an eastern quarter of Grindelwald, near the conjunction of the Schwarze and Weisse Lütschine In 1900, it still reached as far as Rote Fluh (1200 m) and filled the entire valley of its current end, the glacier lake, with a thickness of about 300 m up to an altitude of 1700 m, just below the current hiking path around the Bänisegg. Around 2000 it still reached into the gorge between the Hörnli (Eiger) and Mättenberg.

The Lower Grindelwald Glacier should not be confused with the Upper Grindelwald Glacier, situated to its north-east. The Grindelwald-Fiescher Glacier should not be confused with the like-named Fiescher Glacier, to the south of the Fiescherhorn.
