1970 Map of Little Prairie Lake

About this map

Savanna Portage State Park and the expansive Savanna State Forest dominate this northern Minnesota landscape, centered on the intersection of Aitkin, St. Louis, and Carlton counties. The terrain is defined by the winding course of the Savanna River as it flows north toward the portage, and the Prairie River which meanders through the southern sections. This area preserves a significant historical transit corridor, where early travelers navigated between the Mississippi and Lake Superior watersheds. The presence of a dedicated Snowmobile Trail and Winter Trail highlights the region's adaptation for cold-weather utility and recreation. Smaller water bodies like Little Prairie Lake and Roosevelt Lake are tucked into the heavy forest cover, while an isolated Gravel Pit near the Prairie River provides a rare sign of local industrial activity in an otherwise undeveloped woodland.
