caption_attribution_description: Canyon passage in a cave in Virginia, USA. Skyline Caverns is developed in structurally tilted carbonates (mixed dolostones and limestones) of the Rockdale Run Formation (Beekmantown Group, Lower Ordovician). Cave passages vary significantly in their size, sinuousity, and cross-section shape. Passages that are taller than they are wide are called canyon passages - they form in the vadose zone (above the water table). Locality: Skyline Caverns, Front Royal, central Warren County, northern Virginia, USA
context_page_description: The Beekmantown Group is a late Cambrian to lower–middle Ordovician geologic group that occurs in the eastern Canada and northeastern United States, datable from its conodont fauna. It contains dolomitic sandstones and carbonates from just off land from the palaeocoastline.
  The usage of the term is diverse and depends on the state or region in question, and the group encompasses different formations in different regions. In some states it is considered a formation rather than a group, but the lithology varies by region.
