The ridge-and-valley landscape of the Allegheny Front defines this 1990s record of the border between Clearfield and Centre Counties. The settlement at Sandy Ridge serves as a central point for the region's transport history, where the Conrail line and an Old Railroad Grade navigate the steep ascent of Sandy Ridge. To the north, the industrial footprint of extractive mining is visible through numerous Strip Mines and other extraction sites that pockmark the terrain near Glass City.
