Peirce Lewis, Penn State professor of geography and president of the Association of American Geographers, hosts a journey through the commonwealth's geographic space and historic time -- from Philadelphia in 1682 to Pittsburgh in 1983. The trip emphasizes the diversity of the state, visiting a classic farm and a market town in the Piedmont, a beehive coke oven near Mount Pleasant, Horseshoe Curve near Altoona, the mountains of the central and northern regions, and a countryside ravaged by mining. Produced by Penn State Television / WPSX-TV.
