Abstract: | The most recent glacial history of the Bar Valley on the Batura south side of the great Karakorum main ridge shows a marked
retreat of the Kukuar and Baltar glaciers since 1915 by 8 km. This tendency is continuing. A great lateral moraine (GLM),
which shows the latest, historical maximum postglacial stage, is accompanied by a higher level, which reflects a neoglacial
glacier level whose ice margins no longer exist. An earth-pyramid moraine rising high above the glacier, as also occurs on
the northern declivities of the Batura, does not mark a specific level, but bears witness to a valley-filling glacier, for
which further indicators can be found along the valley flank. In the gorge-like narrow trough valley, the flanks of which
are covered by steep debris cones originating from the postglacial, numerous former glacial characteristics contrast with
the current glaciation of the far retreated Kukuar and Baltar glaciers. Moraine material found at the valley outlet at Chalt
and also on the Talmutz pass demonstrates complete ice filling of the Bar valley, also supported by the Daintar glacier. From
a glacial geomorphological perspective, this confirms a late to high glacial connection of the Bar glacier to a Hunza glacier,
as postulated by Kuhle (2005). |
