About this map

Mille Lacs Lake dominates this 1960s topographic survey, showing the intricate southwestern shoreline and bathymetric depths of one of Minnesota's most significant water bodies. The map details the transition from the open waters of Vineland Bay to the protected forests of Mille Lacs Kathio State Park. This area holds deep historical significance as a cultural crossroads, reflected in the preservation of the landscape around Kathio Point and Rainbow Island.

Navigation and conservation are central themes, with depth curves provided by the Minnesota Department of Conservation. Offshore, the isolated Spirit Island is noted as part of the Mille Lacs National Wildlife Refuge. Along the southern shore, the emergence of local recreational infrastructure is visible at Roadside Park and the small settlement at South Harbor, while smaller interior bodies like Black Bass Lake and Tamarac Lake sit tucked behind the primary lakefront.
