About this map

Mine Ridge dominates the central landscape of this Lancaster County quadrangle, serving as a geological and industrial anchor for the surrounding agricultural townships. The map documents a transition in local infrastructure, showing the Pennsylvania railroad corridor alongside the established path of the Lincoln Highway and Strasburg Road. A significant cluster of activity centers on Nickel Mines, where the extraction history is preserved through labels for the Nickel Mines Mission and the local mine itself.

Social and civic life is traced through numerous scattered institutions such as Middle Octorara Ch, Bart Chapel, and rural schoolhouses like Cedar Hill Sch and Brick Sch. The drainage network, led by Octoraro Creek and its various branches, supported early industry as evidenced by Conners Mill. This mid-century view captures the area after its primary mining boom but before modern suburban expansion began to alter the character of settlements like Gap and Christiana.
