Valley cut by meltwater along Sirmilik Glacier

Location: Bylot Island, Nunavut, Canada

Side of the valley cut by meltwater that created a longitudinal cross-section of the glacier along the axis of Sirmilik Glacier B37. The same valley is shown in images 0030 and 0039. This image shows thrusting of ice under compression in the snout region; the "zig-zag", nearly vertical feature on far wall in upper right corner is another "fossilized" meltwater conduit in cross-section (see also image 0030). In the right center, foreground, the 0.5-m-high escarpment is the trace of a thrust fault that corresponds to the prominent, left-dipping (up ice) thrust fault on the far-side valley face.
