Umsaskis Lake and Priestly Lake dominate the eastern corridor of this remote timberland region, where the boundary between Aroostook and Piscataquis counties divides the landscape. This 2021 survey by the U.S. Geological Survey details a territory defined by industrial forestry and vast hydrographic networks. Primary access routes like Churchill Rd, Poulin Rd, and the Realty Rd navigate the high ground around Squirrel Mtn and Priestly Mtn.
