About this map

Hill River State Forest dominates the southern landscape of this 1970 survey, revealing a Northwoods environment defined by its interconnected hydrology and glacial depressions. The terrain transition is marked by the Itasca Co Aitkin Co boundary, where large bodies of water like Hill Lake and Mountain Ash Lake are interspersed with smaller named features such as Dinner Pail Lake and Previs Lake.

Logistics and recreation in this era are anchored by the Spring Roadside Park along the central north-south thoroughfare. The presence of a Winter Trail in the northwest corner near Little Pokegama Lake highlights the seasonal nature of travel and land use in this part of northern Minnesota. This map captures a moment before significant modern development, where land use was primarily focused on conservation, small-scale extraction as evidenced by local Sandpit and Gravel Pit sites, and the natural flow of Smith Creek.
