Squa Pan Lake dominates this orthophotoquad, which utilizes 1975 aerial photography to document the landscape of north-central Aroostook County. Unlike traditional line-drawn maps, this image provides a direct visual record of timber harvesting patterns and land use at the intersection of water and forest. Along the western edge, the Aroostook River winds through the terrain near the small community of Masardis, where cleared fields contrast sharply with the dense coniferous cover that defines most of the region. The map also reveals the prominent elevation of Brushy Hill to the north, offering researchers a clear view of the wilderness as it appeared during the mid-1970s. This visual record is particularly valuable for identifying historic shorelines and the extent of forest roads that served the local timber industry during this era.
