Crusoe Glacier east sideThe eastern margin of Crusoe Glacier is particularly well accessible from the new basecamp and does not require crossing major meltwater streams. Also, a few hundred metres uphill from Crusoe-Baby Lake, walking on to the glacier surface is possible as the glacier margin is becoming much flatter than lower down. |

The glacier front is advancing and pushing the meltwater channel more and more into the hill on the left. |
![Crusoe Glacier east side Crusoe Glacier east side](icons/glacier_sun.jpg) Ice debris from cliff collapse (right), meltwater falling from the glacier surface (centre) and deeply eroded lateral meltwater channel (left; fisheye lens; July 10th, 2008). | ![Crusoe Glacier east side Crusoe Glacier east side](icons/glacier_waterfall.jpg) After flowing intraglacially, the lateral meltwater channel re-emerges from the ice and forms a massive waterfall which causes an impressive, thundering noise (July 10th, 2008). | ![Crusoe Glacier east side Crusoe Glacier east side](icons/waterfall_miles.jpg) Within four days the water has eroded noticable into the ice, and the waterfall emrges at a lower level. An older, abandoned channel appears further up (July 14th, 2008). | ![Crusoe Glacier east side Crusoe Glacier east side](icons/long_cliff_collapse.jpg) The cliff along the glacier margin has collapsed over a length of several hundred metres (July 6th, 2008; fisheye lens). |
![Crusoe Glacier east side Crusoe Glacier east side](icons/ice_blocks_1.jpg) Recently fallen ice blocks from a cliff collapse are very angular in shape but will get rounded as ablation continues. | ![Crusoe Glacier east side Crusoe Glacier east side](icons/ice_blocks_foliation.jpg) Some of the ice blocks show, in their freshly exposed surfaces, patterns of foliation. | ![Crusoe Glacier east side Crusoe Glacier east side](icons/fresh_collapse.jpg) Fresh cliff collapse a few hundred metres upglacier from Crusoe-Baby Lake (July 10th, 2008). | ![Crusoe Glacier east side Crusoe Glacier east side](icons/glacier_jet.jpg) Water under hydrostatic pressure is jetting out from the surface near the eastern margin of Crusoe Glacier (July 10th, 2008). |
