When sports hunters come to Ellesmere Island, they hunt by dogsled, at least for polar bear hunts. Their hunting area might be far from the community, so the dogs are transported to the hunting area by skidoo. Here's the transport komatik:
I wish I'd gotten a photo of it the day before when it was still loaded up (the dogs were out, but the rest was still loaded). The smaller komatik at the back was loaded on top of the dog cabins with camping gear. It must take a powerful skidoo to pull the load.
