1977 Map of Lac Du Portage

About this map

The Riviere Du Portage winds through this heavily forested borderland, captured in a detailed orthophotograph just before the end of the 1970s. This aerial perspective reveals the dense timber patterns and water systems of the Maine-Quebec border region, where logging and seasonal hydrology define the landscape. Distinct water bodies like Lac Champagne and the small chain of Lacs Oliva are prominent features, surrounded by the textures of regrowth and commercial forest management. The presence of the Frost Pond Flowage and Stony Brook suggests a landscape shaped by both natural drainage and purposeful water control for the region's timber industry. For researchers, the map provides a precise visual record of the shoreline at Hall Pond and the surrounding wilderness before modern reforestation and development cycles altered the forest's composition.
