Mars Hill dominates the southeastern corner of this Aroostook County landscape, providing a dramatic vertical contrast to the sprawling agricultural and riverine terrain of the Aroostook River valley. The map documents an era of intense cross-border and regional connectivity, characterized by the parallel tracks of the Bangor and Aroostook Railroad and the Canadian Pacific Railroad. These rail lines served as the lifeblood for established towns like Easton, Westfield, and Mars Hill, as well as industrial points like Monson Mill.
