Altoona and Hollidaysburg anchor this topographical study of the Allegheny Front, where the legacy of early trans-Appalachian transport remains visible. The Allegheny Portage Railroad National Historic Site preserves the corridor where canal boats were once hauled over the mountain, a feat of engineering that predated the modern rail dominance of the Norfolk Southern line seen winding through Kittanning Gap and around Kittanning Point. From the civic center at the Blair County Courthouse to the outlying industrial history at Allegheny Furnace, the landscape is a complex mix of urban density and steep valley terrain.
