The Pennsylvania State Hospital and School grounds occupy the northern edge of this Venango County landscape, situated where French Creek and Sandy Creek converge near the borough of Polk. The industrial character of the mid-20th century is evident in the dense concentration of oil wells near Raymilton and scattered gas wells throughout the Mineral and Victory townships.
