St Thomas serves as a central hub in this Franklin County landscape, where the agricultural lowlands meet the formidable ridges of the Appalachian Mountains. The terrain is defined by the massive parallel heights of Kittatinny Mountain and Broad Mountain, separated by the secluded Horse Valley. These ridges are punctuated by several natural crossings, including Hendrix Gap and Yankees Gap, which historically dictated travel and drainage patterns toward the W Br Conococheague Creek in the south.
