On the penultimate day of our four-week Mackenzie River canoe trip, the river came within 500 meters of the 68°N 134°W confluence. We suited up in mosquito netting and extra DEET and headed into the bush.
Unfortunately, while it might have been 500 meters as the missile flies, it was considerably longer for us. The undergrowth was impassable in places, and there were many boggy sections that had to be worked around. There was also a small pond directly in the way. It took about an hour each way. The mosquitoes were worse than we had ever seen them, swarming us the entire way.
Once getting there, we spent about 20 minutes chasing the confluence around, until I was able to get a perfect all-zeroes shot of the GPS. Success! A quick set of pictures in the cardinal directions, and we fled back to the relative safety of the river bank where a squadron of dragonflies arrived to beat back the mosquito menace.
