Although some 1,000 to 1,500 feet (300 to 460 metres) lower in elevation than the Mount Rogers highcountry to the east (Mount Rogers is the highest peak in Virginia), the terrain surrounding the High Knob of Stone Mountain forms a true highcountry with respect to the western slopes of the Appalachians in Virginia (i.e., the Cumberland Mountains).

The area around High Knob is dominant structural feature of the Powell Valley Anticline of the Cumberland Mountain Overthrust Block.

With its adjoining faults (Hunter Valley-Clinchport system), this region possesses the greatest concentration of significant caves in Virginia.

High Knob unofficially holds the record for the most snow ever measured in Virginia during a single season, with 200.5 inches (509 cm) during the 1995–96 winter.

On a clear day, four other states can be seen from the summit: West Virginia, Tennessee, Kentucky, and North Carolina.

A tower replacement project was spearheaded by The High Knob Enhancement Corporation who raised required funding from donations.
