This issue's cover: Surface mined landscape described by Haering et al. in "Mapping and Classification of Southwest Virginia Mine Soils," see p. 463-472 Older highwall-bench landforms and associated mine soils are exposed on the steeply sloping sandstone terrain to the right, while the modern landforms in the center-left are being returned to approximate original contour as required by the Surface Mining Control and Reclamation Act of 1977. These mine soils form from blasted sedimentary rock spoils and their chemical and physical properties are strongly controlled by their degree of premining weathering and oxidation. The brown oxidized spoils in the foreground are lower in pH and rock fragments and finer in texture than the gray reduced spoils seen in the middle of the active mine pit.
