Sixtynine Mountain dominates the central landscape of this Somerset County borderland, where the Maine wilderness meets the Quebec frontier. This 1978 orthophotoquad, derived from high-altitude aerial photography, provides a literal visual record of the forest management and drainage patterns in the upper reaches of the Riviere Du Loup watershed. The imagery reveals the stark textures of timber harvesting and regrowth, contrasting the deep shadows of the ridges with the bright, cleared slopes near Bellarmin. Hydrological features like Etang Du Loup and the winding courses of the East Branch Gulf Stream and West Branch Gulf Stream illustrate the natural flow of water through this heavily wooded upland. This document is particularly valuable for tracing historical land use and forest cover before decades of subsequent industrial timber activity altered the terrain.
