1952 Map of Jo-Mary Mountain

About this map

Jo-Mary Mountain and the surrounding wilderness of Piscataquis County are defined by a dense concentration of high peaks and interconnected glacial lakes. In the early 1950s, this landscape remained largely defined by traditional backcountry uses, featuring prominent fire detection infrastructure such as the Wadleigh Lookout Tower and White Cap Mtn Lookout Tower. The Appalachian Trail threads through the topography, connecting the slopes of Nasuntabunt Mountain and White Cap Mountain. This area is characterized by its complex hydrology, where bodies of water like Nahmakanta Lake and Lower Jo-Mary Lake are separated by significant landforms like Potaywadjo Ridge. The survey meticulously documents the township boundaries, including T 1 R 11 and T B R 10, illustrating the formal administrative grid imposed upon this remote timberland and mountain terrain.
