BRAMWELL, W.Va. โ Towering above the valley of the Bluestone River in southern West Virginia, legendary Pinnacle Rock has captivated visitors for millennia. A capstone on a giant wall, it soars more than 120 feet above the spine of Black Oak Mountain in Pinnacle Rock State Park.
But thereโs far more to the rocky tower than meets the eye. While tourists may be accustomed to exploring the rock near the parkโs roadside picnic area, other similar outcrops are located elsewhere in the park, including "Black Rock," an equally large section that rises higher than Pinnacle Rock itself.
The Pinnacle Rock formation also extends far outside the boundary of the park, reaching more than 25 miles across the landscape from Kegley, near Princeton, in the northeast, to Abbs Valley, Va., in the southwest. All along the line, a sharp ridge crested in sandstone extends.
According to geologist Nick Schaer, the remarkable formation is created by "folding," which is the catalyst for the creation of many of the long ridges that extend the length of the Appalachian Mountains in whatโs known as the Ridge-and-Valley Appalachians. The best known of these mountains locally are Peters Mountain and East River Mountains, which form a mountain wall along the state border with Virginia.
Here, folding has raised one of the regionโs famous sandstone layers, the Stony Gap Sandstone, on its end. Perhaps best known where itโs exposed at Sandstone Falls on the New River, 40 miles to the northeast, here that layer has been upended.
โThe Stony Gap sandstone turned straight up into a hog back by the Abbs Valley Anticline,โ Schaer said. The anticline is a geologic fold that in this case forms an elongated trough in the landscapeโa scenic valley of green pastures.
โAt the center of the anticline, the Stony Gap Sandstone is eroded away, exposing the Greenbrier Limestone. This is the bedrock of Abbs Valley.โ
An anticline, beneath the surface, typically resembles an "A" shape, with the oldest rock layers at its core and younger layers draped over them. The layers dip away from the central axis of the fold, which is known as the hinge line, in this case at the center of the Abbs Valley.
Anticlines are often formed during mountain-building processes when tectonic plates collide and create compressive stress, forcing the rock layers to deform into an arch-like fold. Imagine a stack of paper being pushed together from both ends.
The rock at the center of the arch is often weak and apt to form valleys, while those at the sides of the fold, also known as the limbs or flanks, remain more resistant to erosion. However, Schaer said folding and upheaval in the region is complex and an alluring puzzle to geologists.
โThe flanks of the anticline have a lot of faulting that makes stratigraphy very tricky in that area,โ he said.
Similar, though smaller, rock formations can be found along the line. Turkey Rock and Black Rock are located within the park. Black Rock, to the northeast of Pinnacle Rock, is the most lofty and was first known as โThe Pinnacle.โ No official park trail leads to it. Turkey Rock is smaller, a half mile southwest of Pinnacle Rock, and is the focus of the parkโs 1.5-mile Turkey Rock Trail.
Other smaller formations can be found along the line of the crest of Black Oak Mountain far beyond the park, and in places, the outcrop is no more than a sharp, stony ridge line. Highway US-19 near Kegley notably crosses two folded ridges over which motorists must ascend and descend.
The birth of Pinnacle Rock State Park
Although Pinnacle Rock is a stunning natural landmark, its preservation required a determined fightโa fight that ultimately led to the creation of Pinnacle Rock State Park.
At the time, in 1931, highway engineers building US-52 proposed blasting through the rock. And while the new road promised to improve commerce, community leaders recognized the value of the rock as a tourist attraction.
Among the first to act was entrepreneur and politician Hugh Ike Shott, who sent a letter to Governor William G. Conley urging action. Conley intervened, and engineers decided to raise the roadbed rather than destroy the rock.
Inspired by Shottโs success, civic leaders soon began developing plans for a park, and in 1938 the West Virginia Conservation Commission and the Bluefield Chamber of Commerce announced the acquisition of 28 acres.
Development began in 1939, with the construction of trails, walkways, and picnic facilities, including a pavilion and restrooms. Funded with more than $13,000 from President Franklin D. Rooseveltโs Works Progress Administration, federal workers used locally sourced stone and timber to build the enduring structures that remain a beloved feature of the picnic.
Today, Pinnacle Rock State Park encompasses more than 370 acres, including the mountaintop and its rock outcrops as well as mountainside forest and Jimmy Lewis Lake, a five-acre fishing lake and wetland. More than six miles of hiking trail now wander the park, and a system of stairs climbs to an observation area at the top of Pinnacle Rock.
Though Pinnacle Rockโs rugged sandstone face would seem a magnet for rock climbers, climbing is not permitted because of the fragmentation of the stone. Photographers, however, will find the rocks, picnic area, and remote reaches of the park an invaluable source of subject matter.
Native animal species, including deer, wild turkey, and the occassional bear, roam the park, as do smaller animals such as racoons, opossom, squirrels, and ground squirrels.
Pinnacle Rock State Park offers a mix of natural beauty, recreational opportunities, and a glimpse into Appalachian geology. For those passing through southern West Virginia, itโs a destination that promises both inspiration and tranquility.
