The New York Central River and the Susquehanna West Branch carve through this section of the Allegheny Plateau, defining a landscape of deep hollows and narrow ridges during the late 1920s. Industrial activity is concentrated in the southern portion of the quadrangle, where the New York Central Pennsylvania railroad serves the coal-producing regions near Clarence Snow Shoe Sta. Numerous mining operations, such as Mine No 26 and Mine No 22, indicate the extractive economy that fueled settlements like Snow Shoe and Gillintown.
