Thanks for the report. I canoed from Wollaston Lake via the The Thlewiaza river to Neulton Lake a few years back. We saw a lot of moose. Had you more time, I'm sure you would have gotten a bull. Caribou numbers have dropped dramatically in the past 10 years. Also, the caribou seem to be spending more time further north, along Hudson Bay in the North West Territories. NWT has closed its season for sport hunting. Collecting your carbon may be tough given the changes that have occurred.
By the way, we call Black flies and mosquitoes "Protectors of the North" ....if it wasn't for them, everyone would want to live in the North and it would start resembling California!
Enjoyed your report, even though you weren't successful. That's hunting.
