2018 Map of Umsaskis Lake West

About this map

Umsaskis Lake and Priestly Lake anchor this North Maine Woods landscape, representing a remote corridor defined by water and timber management. The terrain is dominated by significant elevations such as Squirrel Mtn and Priestly Mtn, which overlook a complex network of drainage systems including Priestly Brook and Drake Brook. This region spans the border of Aroostook and Piscataquis counties, a line that cuts through dense woodlands where infrastructure is limited to private forestry routes like Realty Rd and Poulin Rd. The presence of these named logging roads and the intricate mapping of the various branches of Middle Br Thoroughfare Brook highlight the area's importance for commercial timber access. For the researcher, the map provides a precise look at the hydrology feeding into the Allagash Wilderness region, from the shores of Little Churchill Pond to the northern flow of Squirrel Brook.
