Stony Mountain dominates the central landscape of this Lebanon County quadrangle, dividing the northern drainage of Clark Creek and DeHart Reservoir from the developed corridors to the south. The southern half of the map is defined by the expansive military installation of Fort Indiantown Gap, which is marked by a complex network of tactical roads like Ammo Rd and Fogarty Rd. This area reflects the mid-20th-century expansion of military infrastructure into the rural Pennsylvania countryside.
