1. Peach Bottom Slate Region Marker
Inscription.  A ridge of high quality slate running from southeastern Pennsylvania into Harford County, Maryland, was quarried on a limited scale as early as 1734. Production increased in the 1840s when the opening of the Susquehanna and Tidewater Canal offered a link to markets, and skilled slate workers were recruited from Wales. Rail transport replaced the canal in 1876. Quarries continued to operate into the early 20th century. Peach Bottom slate was widely renowned for roofing.
