The Monongahela National Forest includes some major landform features such as the Allegheny Front and the western portion of the Ridge-and-valley Appalachians. Within the forest boundaries lie some of the highest mountain peaks in the state, including the highest, Spruce Knob (4,863 ft). Spruce Knob is also the highest point in the Allegheny Mountains. Approximately 75 tree species are found in the forest. Almost all of the trees are a second growth forest, grown back after the land was heavily cut over around the start of the 20th century. Species for which the forest is important include red spruce (Picea rubens), balsam fir (Abies balsamea), and mountain ash (Sorbus americana).

The Monongahela National Forest includes eight U.S. Wilderness Areas and several special-use areas, notably the Spruce Knob–Seneca Rocks National Recreation Area.

Geography

The Monongahela National Forest encompasses most of the southern third of the Allegheny Mountains range (a section of the vast Appalachian Mountains range) and is entirely within the state of West Virginia. Elevations within the Monongahela National Forest range from about 900 feet (270 m) at Petersburg to 4,863 feet (1,482 m) at Spruce Knob. A rain shadow effect caused by slopes of the Allegheny Front results in 60 inches (1,500 mm) of annual precipitation on the west side and about half that on the east side.

Headwaters of six major river systems are located within the forest: Monongahela, Potomac, Greenbrier, Elk, Tygart, and Gauley. Twelve rivers are currently under study for possible inclusion in the National Wild and Scenic Rivers System.
