"Ablation Valley Glacier"This small un-named glacier flows from Io Peak and low mountains to the west, and displays a wide range of interesting features. Its tongue is divided by a large elevated area, informally named "The Mound", that has remained ice-free for a long time. | |||
 The two tongues of "Ablation Valley Glacier" on either side of a drift-covered bedrock mound. |  Fluted margin of the glacier, resulting from differential ablation and meltwater. |  Several ice avalanches were observed at the head of the glacier. Here a slab of ice has detached completely from the bedrock on Io Peak. |  An avalanche from ice cliffs on the crest of the west ridge of Io Peak. Note the run-out distance of the main avalanche, and the ice-boulders that extended even further. |
 "Ablation Valley Glacier" and its accumulation area on Io Peak, seen from frozen Ablation Lake. A large ice-cored moraine complex is visible on the left. |  The ice-free headwall at the back of the glacier, and the zone where the ice tongue splits. "The Mound", with moraines is on the left. |  Ice towers on "Ablation Valley Glacier", which are the result of differential ablation of dirty and clean ice. |  Ice pinnacle at the apparent margin of "Ablation Valley Glacier". |
 Melt-pool at the apparent margin of "Ablation Valley Glacier", looking up-glacier. |  The same melt-pool looking our towards George VI Ice Shelf. |  The rough surface of "Ablation Valley Glacier", resulting from differential ablation. |  Large supraglacial erratics of Jurassic-Cretaceous conglomerate occur near the snout of "Ablation Valley Glacier". Note the person for scale. |
 Large supraglacial erratics of Jurassic-Cretaceous conglomerate and sandstone on the surface of "Ablation Valley Glacier", looking towards the source cliffs. |  A view of the erratics in context, with Io Peak in the background. |  Close-up of the conglomerate in one of the erratics. The well-rounded appearance suggests deposition in a high-energy fluvial setting. |  A large bedrock "raft", detached by the glacier, transported and deposited in the terminal moraine complex. |
 The receding margin of "Ablation Valley Glacier", with characteristic ice ridges and pinnacles resulting from differential ablation. Large mounds of ice-cored moraine occur in front of the glacier. |  Steep margin of "Ablation Valley Glacier", with incised ice-marginal meltstream. A small amount of meltwater is flowing in this early summer (November) photo. |  Runnels formed by small streams on the steep snout of "Ablation Valley Glacier". |  Moraine of sandy gravel at the bifurcation zone of "Ablation Valley Glacier", adjacent to "The Mound", with Io Peak in the background. |
 Englacial cobble- and pebble-sized debris emerging from the snout of the glacier. None of this debris shows direct signs of glacial modification, suggesting that the glacier is cold-based. |  Moraine containing a cluster of large pale sandstone boulder adjacent to “The Mound”. Note the steeply dipping and folded Jurassic-Cretaceous strata in the background. |  A laminated sandstone in moraine that has suffered severe frost-shattering. |  A chemical precipitate of unknown composition, formed on a sandstone boulder in moraine. |
 The boundary between the steep scree slopes and ice-cored moraine, both made up of Jurassic-Cretaceous conglomerate. |  Hummocky moraine below the snout of "Ablation Valley Glacier". This moraine is ice-cored. Beyond is Ablation Lake and George VI Ice Shelf. |  "Moraine art" created by Ian Hey. The well-rounded stones have weathered out from the Jurassic-Cretaceous conglomerate. |  A giant block of conglomerate in the moraines below "Ablation Valley Glacier". Io Peak in the background. |
