Mountain Top sits at elevated terrain in the Back Mountain region of Luzerne County, where unique geological conditions create significant radon risks. Located at the foothills of the Pocono Mountains, the area's higher elevation and underlying bedrock formations of the Allegheny Group contain uranium-bearing shales and sandstones that naturally produce radon gas.
The community's position on glacially-carved terrain means homes are often built on fractured bedrock and glacial till deposits that create natural pathways for radon migration. Mountain Top's topography includes numerous ridges and valleys that can trap radon-laden air, especially during temperature inversions common to elevated areas.
Many Mountain Top homes feature walk-out basements and foundation configurations designed for sloped terrain, which can create multiple entry points for radon gas. The area's well-drained soils, while good for construction, can also facilitate radon movement from deep underground uranium sources to home foundations.
