The West Branch Union River, Middle Branch Union River, and East Branch Union River converge in this corner of Hancock County, defining a landscape of glacial ridges and complex drainage systems. The small settlements of Amherst and Aurora are positioned along the high ground, while the southern reaches near Waltham and North Mariaville follow the river corridors. Of particular interest is the prominent esker known as The Whalesback, a classic post-glacial formation that dictates the path of local travel and drainage. The interior is marked by significant elevations like Silsby Hill and Moose Hill, interspersed with isolated water bodies such as Giles Pond. This map documents a period when the local economy remained tied to the timber and river network, with numerous brooks like Archer Brook and Joe Moore Brook feeding into the primary branches of the Union River.
