2014 Map of Umsaskis Lake East

About this map

The Allagash River flows through this remote stretch of the North Maine Woods, marking the geographic heart of the region's wilderness waterways. This 2014 survey captures the landscape at a time when access remained limited to industrial logging routes like Reality Rd and Churchill Dam Rd. The boundary between Aroostook and Piscataquis counties bisects the area, cutting across the southern reaches of Umsaskis Lake. Small tributaries including Harrow Brook and McCluskey Brook drain into the main river corridor, which remains the primary artery for travel through the heavy forest. The map detail highlights the hydrological connection between Priestly Lake and the surrounding drainage basins of the N Br Glazier Brook, illustrating the complex network of wetlands and streams that define this protected timberland environment.
