Description
The Northwest Territories ice roads — winter highways over frozen lakes and rivers that are the only land access to remote communities and mining operations — are among the world’s most distinctive seasonal transportation phenomena. The aerial perspective at 200 metres reveals the ice road’s relationship to the lake geometry: the track runs in a straight line across the frozen lake surface, the compressed snow of the wheel tracks visible as a pale grey ribbon against the white ice. Pressure ridge cracks in the ice — natural features of lake ice under the thermal stress of winter temperature cycles — cross the road at intervals, visible as dark linear features in the ice surface. An approaching supply truck is visible as a small dark square on the road ahead. The lake’s far shore is just visible at the frame edge, communicating the 30- kilometre crossing distance. Shot from 200 metres at noon, the low winter sun casts long shadows from the pressure ridges across the ice surface.
