Tyrone serves as the industrial and transportation nexus where the Little Juniata River cuts through the ridges of central Pennsylvania. The 1921 survey reveals a landscape defined by the legacies of early iron production and complex hydraulics, evidenced by the presence of Huntingdon Furnace and Pennsylvania Furnace, alongside the enduring path of the Frankstown Branch Pennsylvania Canal. The intricate network of the Pennsylvania Railroad follows the natural corridors of the Bald Eagle Valley, connecting numerous small settlements like Ironville, Warriorsmark, and Petersburg.
