Geography
The Dart Glacier has a fairly typical morphology, including a clearly defined
The topography and climate of the Dart Glacier make it particularly responsive to changes in conditions. Since 1915, the glacier has retreated approximately 3.5 kilometres (2.2 mi), with historical records from the time showing the glacier extending further down the Dart Valley, connecting with the Hesse and Marshall glaciers in the process.[4] Fieldwork during the 1980s also discovered pockets of ice from the glacier buried beneath a layer of gravel 10–15 metres (33–49 ft) in the Dart Valley, near where the glacier's terminus would have been in the late 19th century.[5] The ice was estimated at 80 metres (260 ft) thick at the time of the study, though sinkholes on the surface indicated that the ice was decreasing in volume.
