Yesterday while down at Duluth’s Canal Park, I noticed that a flock of Goldeneyes would fly into the canal 20 to 25 minutes before dawn to start their morning feed in one of the few spots with open water (Lake Superior is 90% ice covered as of yesterday). The open water is due to the combination of current present in the canal as water flows out into Lake Superior, and our prevailing winds out of the west and northwest tend to push water away from the Duluth harbor which causes an upwelling of “warmer” water.
Regardless, it was a beautiful icy cold morning (0F with a 15 mph wind).
