(MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/02_morteratsch_tele.jpg) Medium telephoto of Vadret da Morteratsch, illustrating a massive icefall, the main glacier tongue and its debris-covered tributaries (including Vadret Pers on the left), viewed from Laghalb in September 2008. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/03_medial_moraine.jpg) Strong telephoto of the confluence zone of Vadret Pers (left) and Vadret da Morteratsch (right) in September 2008, with prominent medial moraine between them.

![Glacier tongue 2008 Glacier tongue 2008](icons/05_meteo_station.jpg) A small temporary meteorological station set up on Vadret da Morteratsch by Aberystwyth MSc Glaciology student, Andrew Fitzpatrick, to investigate the response of supraglacial streams to weather conditions. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/06_morteratsch_drilling.jpg) Hot-water drilling system demonstrated by Aberystwyth PhD student, Richard Farnell, on Vadret da Morteratsch to allow insertion of stakes for recording velocity and ablation. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/07_drilling_steam.jpg) The drilling system with the drill-head emitting a powerful jet of steam that allows rapid melting of a hole in the glacier surface to several metres. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/08_morteratsch_drilling.jpg) Drilling on a glacier for any length of time can be a cold job. Here we see the burner on the left, a stake being inserted and various wires connected to the meteorological experiment. In the background is the disappearing icefall of Vadret Pers. (MH) |
![Glacier tongue 2008 Glacier tongue 2008](icons/09_morteratsch_snout_collapse.jpg) Telephoto of the central drainage system at the snout of Vadret da Morteratsch. Water disappeared down a moulin and in this 2008 image, and provided temporary access to an under-ice cave system. The ring of dirty ice around the snout represents ‘basal ice’ comprising debris frozen on the base. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/10_morteratsch_portal_context.jpg) Being in close proximity to snout of Vadret da Morteratsch reveals an extensive spread of rubble with little vegetation and channels containing sediment-laden meltwater; September 2008. (MH) | ![Glacier tongue 2008 Glacier tongue 2008](icons/11_morteratsch_portal_2008.jpg) The glacier portal (about 4 m high) at Vadret da Morteratsch in September 2008. (MH) | |
