I'm living in Tulit'a now, but have been traveling all over the Sahtu Region, including up above the Arctic Circle (I was in Colville Lake last week and it was -45!). We have a nice 5 k loop from our office in Tulit'a that goes around the airstrip outside of town. It has been skidoo'ed in, and we track it in a few times a week. We consistently see lynx, wolf, ptarmigan, and snowshoe hare tracks on our trail.
