In addition to winter operations, trap lines need to be maintained in the summer for winter use. Brush removal, trees cut, new lines cut. Not an easy job.
Looks to me like he is following the rules. Primary Structure must not exceed 576sq ft. Must not occupy more than 1 acre, shed should not be larger than 12’ x 12’.

Looks like he puts pride into the property to make it look good.
Nice cabin. I would spend time there, as I’m sure most who love the area would.
He probably paid a hefty price for those trapping rights.
I find most trappers to be salt of the earth types, with a plethora of info about the area. Stop in and say hi next time, I’m sure he will chat your ear off.
