The scenic Holmes Run Gorge is one of the most floristically and geologically diverse areas of northern Virginia. Massive cliffs and outcroppings of bedrock abound, capped by ancient gravel terraces and deposits of the Potomac Formation. The vegetation of the Gorge is diverse, with old-age forest stands and many species that are uncommon to rare in the region.
For more on the geology of the Holmes Run Gorge, see the greatly revised and improved digitized Geologic Atlas of the City of Alexandria, Virginia and Vicinity at https://www.alexandriava.gov/89974.
