The transition from agriculture to an industrializing landscape is evident around Erie, where coal extraction once dominated the economy. By 1950, many sites like the Columbine Mine and State Mine were already marked as inactive, yet they remain critical markers for local history and genealogy. The map captures the complex water management system essential to the region, featuring the Liggett Ditch and Lower Boulder Ditch which crisscross the plains near settlements like Canfield and Tabor.
