Crusoe Glacier east side
The 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.

Snout of Crusoe Glacier on a warm day with strong runoff (July 2nd, 2008).
Massive meltwater stream from Crusoe Glacier emerging from a small gorge and entering the outwash plain.
Masses of broad-leaved willow herb (Chamaenerion latifolium) in the sheltered valley in front of Crusoe Glacier's snout.
Ice cliff at the terminus. The glacier front is advancing and pushing the meltwater channel more and more into the hill on the left.
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).
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).
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).
The cliff along the glacier margin has collapsed over a length of several hundred metres (July 6th, 2008; fisheye lens).
Recently fallen ice blocks from a cliff collapse are very angular in shape but will get rounded as ablation continues.
Some of the ice blocks show, in their freshly exposed surfaces, patterns of foliation.
Fresh cliff collapse a few hundred metres upglacier from Crusoe-Baby Lake (July 10th, 2008).
Water under hydrostatic pressure is jetting out from the surface near the eastern margin of Crusoe Glacier (July 10th, 2008).
Exposed bedrock, cleared from moraine, indicates that Crusoe Glacier has begun thinning up here, approximately 500 metres upglacier from Crusoe-Baby Lake.
Gently undulating glacier surface below a small icefall of Crusoe Glacier (July 10th, 2008). Colour Peak is visible at the image centre.
Caribou teeth found on Crusoe Glacier (July 10th, 2008).

Meltwater pond formed on a closed crevasse below a small icefall.
Looking downglacier; Little Matterhorn and Bastion Ridge in the far distance (July 10th, 2008).
After a day's fieldwork the camp is a welcome sight beyond the gorge in front of Crusoe's snout.
