The West Br Susquehanna River serves as the central artery for this Lycoming County landscape, separating the dense grid of Newberry and the industrial corridors of Williamsport from the southern settlements of Duboistown and Nisbet. The map reveals a sharp transition from the urban developments along Wahoo Dr and Reach Rd to the steep, wooded slopes of Jacks Mountain and Raccoon Mountain. This geography is defined by a system of narrow valleys and hollows, such as Fox Hollow and Bear Pen Hollow, which historically channeled local development and water management. Significant infrastructure for the region's water supply is evident in the Mosquito Valley Reservoir and Mosquito Run Reservoir. The southern portion of the sheet remains largely rural, where the remote French Settlement and the village of Elimsport anchor a landscape of winding runs and mountain trails.
