regions of Nunavut Interesting.
If you look up the regions of Nunavut on Wiki
https://en.wikipedia.org/wiki/List_of_regions_of_Nunavut
it looks to me like Back River, and Probably Hackett also, appear to be in the Kivalliq region rather than Kitikmeot.
That might be a good thing to ask Sabina some time. Maybe the map is somewhat inaccurate or maybe Kitikmeot has some "panhandles" that were created to encompass these properties that the map is too crude to show in detail.
