I've been trying to figure out all the fire history. If I'm correct, most of McNiece burned in 2007-ish. A lot of the big white pines survived. There are pockets on the east side of the lake by the eastern campsite that were totally unscathed but the rest of the lake was hit. I think the west side and portage burned again in 2011 when there was the Kahshahpiwi fire.
The portage has clearly been cleared since both fires, but it appeared it hasn't gotten any maintenance in at least a year.
