1999 Map of Slatedale

About this map

Blue Mountain and the ridge-top Appalachian Trail dominate the northern horizon of this Lehigh County landscape. Below the slopes, the topography reveals a transition from the industrial legacy of quarries near Slatedale and Emerald to the agricultural valleys of Heidelberg, Lynn, and Lowhill. The map preserves the names of numerous nineteenth-century rural centers, including Lehigh Furnace and Germansville, alongside established community hubs like Heidelberg Ch and Lowhill Ch. The drainage patterns of Jordan Creek and Trout Creek define the movement through these ridges, while the southern portion of the sheet is marked by the expansive Trexler Game Preserve and State Game Lands No 205. This layout reflects a century of land use, where slate extraction in the north gave way to conservation and traditional township settlements that remain anchored by local landmarks such as Werleys Corner and Newside.
