The Clarion River snakes through the heart of this Pennsylvania landscape, serving as a primary geographic anchor for the borough of Clarion and its surrounding communities. The presence of the Clarion University of Pennsylvania defines the northeastern portion of the map, while the Clarion County Airport and Groce Hill overlook the river valley from the west. Engineering is evident at Piney Dam, which alters the river's flow near the junction of several rural routes.
