1964 Map of Bull Island

About this map

Flathead Lake dominates this mid-1960s study, showcasing the intricate shoreline where the water meets the Finley Point peninsula. The map details the complex geography of the southern lake region, specifically focused on the restricted passages of The Narrows and the clustering of landforms including Bull Island, Little Bull Island, and Bird Island. The eastern shore is characterized by a series of significant inlets such as Yellow Bay, Sunset Bay, and Blue Bay, which serve as catchments for drainage systems like Hellroaring Creek and Boulder Creek. A designated State Park at the northern edge of this sheet indicates early recreational development along the lakefront. Prepared for the Bureau of Indian Affairs, the survey illustrates the intersection of natural topography and managed lands within the reservation, capturing the specific shoreline configuration before later decades of development.
