Wormald Ice PiedmontAn ice piedmont is a glacier that forms at the foot of a range of mountains with a front that is longer than the distance along the flow centerline. Wormald Ice Piedmont (67°29'S, 68°5'W) covers most of the eastern part of Wright Peninsula, Adelaide Island, and is named after a meteorologist of the British Antarctic Survey. The 25 km-long ice piedmont is close to Rothera Research Station, and as such is used as an emergency airfield as well as a training ground for field parties. |
Aerial view of the SW end of Wormald Ice Piedmont, showing marine-terminating cliff, the Rothera runway and station buildings, and Rothera Point (centre). | Ice cliff of Wormald Ice Piedmont, with icebergs and new sea ice in the foreground, seen from Rothera Point. | Telephoto of ice cliff seen beyond three icebergs. Crevasses above the ice cliff indicate where the next calving event will occur. | View from the surface of Wormald Ice Piedmont, looking towards Mackay Point, where the ice is grounded, and beyond to Arrowsmith Peninsula on the mainland. |

Note the piles of ice rubble at the foot of the cliffs. | Close-up detail of the calving front of Wormald Glacier near Mackay Point. | Stratification and cornices at the southwestern ice cliff next to the Rothera runway. |
