I believe this is a Canadian production so they were limited to Canada. The weather is a real killer, but had they shot in a more hospitable area they still be there as you say. The other area that comes to mind is Labrador. The black files there would drive them screaming from the bush.
There's talk of them going to Patagonia next season.
Certainly does help having seen S1 - gill net, axe, saw, ferrio, cordage and extra food. That leaves 4 items for fun.
Side note -...
