About this map

Kittatinny Mountain and Broad Mountain dominate the northwestern landscape of this Franklin County region, separated by the narrow McCasslin Valley. This 1944 survey, updated with 1968 aerial revisions, shows the rural character of the Cumberland Valley before significant modern development. The community of St Thomas sits along Route 30, while smaller historical nodes like Franklin Furnace and Edenville flank the eastern slopes of the ridgeline.

Drainage patterns are clearly defined by the W Br Conococheague and its tributaries, such as Campbell Run and Wilson Run. To the north, the Letterkenny State Forest covers the steep timberland, marked by high points like Parnell Knob and geological breaks including Yankees Gap and Hendrix Gap. The presence of a major Pipeline cutting across the agricultural southern flats provides a glimpse into the mid-century infrastructure improvements in central Pennsylvania.
