It IS legal to hunt at night, using "natural light" IIRC. No electronic gizmos allowed tho. . We don't have "shooting hours".
I've seen winter nights with moonlight on snow that were bright enough for shooting out to 200-300 yard. Never done it tho.
I would hazard a guess that using thermal imaging to asses what animals are in the area is as legal as trail cameras, some of which are.
Just not for actually using them to shoot an animal, but that's just a guess. Too lazy/ don't care enough to inquire further.....

Yes of course. I wasn't thinking ALASKA. I remember being at the medical camp (14,200') on McKinley in June. It never really gets dark. The sun goes behind the mountain and the temp drop dramatically. But the "white nights" are as bright as day in the shade.
