1977 Map of Black Mountain

About this map

Tim Pond sits at the base of the highlands in this remote corner of Franklin County, where the 1977 aerial imagery reveals a landscape shaped by high-elevation drainage and timberland. This orthophotograph, produced by the Geological Survey, captures the textured forest canopy across Black Mountain and Bob Mountain during a late October flight. The drainage patterns are particularly clear, showing the headwaters of the North Branch Alder Stream and South Branch Alder Stream as they carve through the terrain. Unlike traditional topographic maps, this imagery provides a direct view of the land cover and logging access routes as they existed in the late 1970s, anchoring the relationship between landmarks like Maple Hill and the adjacent water bodies of Big Sag Brook and Black Brook.
