This map stands out for its detail. The states rugged Appalachian Mountains are clearly visible (particularly in the eastern part of the state), showcasing the difficulty early settlers must have had when venturing west. The key (top right) indicates map labels for houses of worship, forges, and even Indian towns, providing some insight into each towns importance. The map also has separate markers for county and township borders, as well as for roads that form county and township lines.
Notice that the maps key and some of its titles have German translations. According to David Rumsey (which has an online copy of this map), the map is part of a US atlas created by German mapmaker Daniel Friedrich Sotzmann, who intended to create an 18-map collection but only finished 10. The mapmakers German origins is appropriate; since its founding, Pennsylvania has been home to a prominent Pennsylvania Dutch community of German-speakers from central and southeastern Europe.
