The Yew Mountains run as a long ridge through southern Pocahontas County and into neighboring counties. Geologically, they mark a transition: to the southeast the ground drops away to the Ridge-and-Valley Appalachians, with their parallel folded mountains and clear valleys. To the northwest the ground falls more gradually into the Allegheny Plateau, a deeply dissected landscape of rolling hills and steep hollows that is geologically older but topographically less dramatic. Standing on the spine of the Yew Mountains, you can look east into the broken corrugated country of folded sedimentary rock, and west into the country where streams have spent 200 million years cutting their way down through a sandstone tableland. The ridge is the seam between two ways the Appalachians have weathered.

The highest point in the range is Red Spruce Knob, at 4,703 feet above sea level - the ninth highest peak in West Virginia. It is named for the stand of Picea rubens, the red spruce, that still grows at the summit. Red spruce was once the dominant tree of the central Appalachian highlands above about 3,500 feet, but the logging boom of the 1890s through 1920s cut nearly all of it. The hardwood forest that grew back replaced spruce with cherry, birch, and maple in most places. The summit of Red Spruce Knob is one of the small remnant populations - a relic ecosystem of mountain spruce surviving where the logging crews could not quite reach it. The Highland Scenic Highway crosses the knob, making it the highest point on that road as well.

Beyond Red Spruce Knob, the range includes Black Mountain, Jacox Knob, Briery Knob, and Blue Knob. These are not dramatic peaks in the alpine sense - no exposed rock, no glaciers, no above-treeline ridges. They are rounded summits covered in northern hardwood forest, with views that open only where the timber happens to be thin or where a deliberate clearing has been made. To hike them is to walk through the kind of eastern mountain forest where the experience is intimate rather than grand: the smell of wet leaves, the sound of warblers, the occasional sudden glimpse of the next ridge through a gap in the trees.

Most of the Cranberry Wilderness, the largest wilderness area in the Monongahela National Forest, lies within the Yew Mountains. The Cranberry Glades, the largest peat-bog complex in West Virginia, sits in a high valley between the peaks. The Yew Mountain Center, a private nonprofit education facility near Lobelia, offers programs in natural history and Appalachian culture from a 500-acre site on the range. The combination of federal wilderness, scenic highway, and educational center makes the Yew Mountains one of the most concentrated areas of intentional landscape preservation in the state. It is, in effect, a wilderness with infrastructure - which is to say, a wilderness designed for people willing to make some effort to reach it.

The proposed Birthplace of Rivers National Monument would consolidate the existing federal protections in this area under a single designation, formally recognizing the headwaters of the Cherry, Cranberry, Williams, Gauley, and Greenbrier rivers. Conservation advocates have been pushing for the designation since the early 2010s. The proposal has stalled and revived more than once, depending on the administration. The land is already largely protected as Monongahela National Forest and as wilderness; the monument designation would mostly elevate the visibility and provide a unifying name. Whether or not it happens, the rivers will continue to start here. The water has been doing this for longer than the politics has been arguing about it.
