Lac la Croix Research Natural Area, Protected natural research area in Minnesota, United States
Lac la Croix Research Natural Area is a protected natural research zone in the Superior National Forest near Minnesota's border with Canada. The area spans dense forests of red and white pine trees that characterize this northern woodland region.
The area was designated as a Research Natural Area by the US Department of Agriculture in 1942 to protect its untouched pine forests. This designation helped preserve one of the last remaining original forest sections in the northern region.
Native American communities maintained strong connections with the lands surrounding Lac la Croix, utilizing its natural resources for generations.
Entry to certain sections requires permits that can be obtained through the local Forest Service office. The best time to visit is during warmer months when access and trail conditions are most favorable.
This site preserves one of the last unaltered stands of old-growth pine forest in the northern region that has remained largely untouched by human activity. Scientists use this location to study how natural forests function without human intervention.
