Explorers find pristine wilderness

Two Australian explorers, twenty-five-year-old Chris Bray and Clark Carter from New South Wales, say they have completed a world-first trek across Victoria Island in the Arctic.

The two crossed the widest point of Victoria Island, in Canada's north, observing wildlife that had never seen humans before.

They say wolves and polar bears ...

Mr Bray told reporters he felt the 600 kilometres travelled across snow, mud plains and rapids was completely unexplored.

He said while the local Inuit people had been over some of the island, he thought no-one had walked across the island at its widest point.
