"Officials in a remote Baffin Island community said Saturday conditions appear to have stabilized after a flash flood looked as though it might wash the community away from underneath.
Heavy rain and unusually warm 13-degree temperatures produced rapid snow melt in the surrounding mountains and hills and led to a flood last weekend.
So much water blasted down the Duvall that it carved a 10-metre channel through the permafrost, right down to bedrock. It damaged both of the town's bridges sufficiently that a majority of the community's 1,600 residents were cut off from the water reservoir, sewage lagoon and garbage dump.
Fears of subterranean erosion were then raised as large cracks and sinkholes began to appear between the town and the river.
"More large cracks (were) appearing, more sinkholes,'' said Mongeau. "We had a telephone pole that literally, before our eyes, dropped 15 feet into the ground.''
With more rain and warm temperatures forecast, Mongeau is unsure whether the current stability will last.
"At this point they're stable; tomorrow, who knows,'' he said.

Private geo-tech companies should be on site shortly to use ground-penetrating radar to find out exactly what's stirring beneath their feet. Science professionals already studying the situation are dumbstruck by what's happening.
Although Mongeau stresses his opinion is not scientific, he believes the root cause of this occurrence, and many other in the eastern Arctic, is global warming. He said ice patterns have been shifting and locals are noticing the arrival of new species to the area, like capeline -- a small fish used to catch cod.
"Fishermen have been fishing these waters for 40 years and they've never seen one,'' he said. "We're pulling them out in large numbers right now.'' LINK
