the practice of burying cave burials, along with ceremonial earthwork complexes, were a part of the Mississippian culture brought into Southwestern Virginia from Alabama and Tennessee

Over 50 mortuary caves in Virginia have been identified between the Tennessee border and Montgomery County. In addition, one mortuary cave in Page County with remains of five people, including a pregnant woman with a fetus, was documented by archeologists in 1939-40. The distance between that cave and the Southwest Virginia burial caves requires a 150-200 mile walk.1
In the calcium-rich caves in the Valley and Ridge physiographic province, bones have survived even though modern visitors and vandals have disturbed almost every cave burial site. If there were cave burials in Virginia prior to the Woodland Period, they have not been discovered.
Bone fragments discovered within a stalagmite in Luray Caverns is estimated to have been inside the cave for 500 years, based on the speed at which the calcite accumulated around the bones. a burial may have dropped down from the surface through a sinkhole rather than been placed intentionally in the cave. Tourists still walk through "Skeleton Gorge" when visiting the caverns, but the stalagmite with the bone fragments was sent to the Smithsonian Institution in 1920.

During the Mississippian Period (800-1600CE), Native Americans living in the Southeast from Alabama to Tennessee buried some people in caves as well as in ceremonial mounds. Migration of people, or cultural diffusion through trade and marriage, carried the cave burial practice across the watershed divide from the Tennessee River to the New River:2

The Marginella Burial Cave Project started in 1992. Its researchers have worked with law enforcement personnel, cavers, landowners, and state agencies to protect caves and minimize disturbance of underground archeological resources. Scientific exploration is constrained by modern sensitivities and the Native American Graves Protection and Repatriation Act (NGPRA), but remains from approximately 400 people have been identified from caves in Southwest Virginia. Farley's Cave in Lee County, Elk Garden Cave in Russell County, and Higgenbothan Cave in Tazewell County each may have included the remains of 100 or more people.
Natural holes in the ground could have been viewed as portals for passage on the journey to whatever afterlife was envisioned. Some human remains were found in the "twilight" area of a cave near the entrance, while in other cases the remains had been carried into the "dark" zone requiring artificial light such as burning sticks or reeds. At least one burial was placed on a ledge 15 feet above the cave floor, suggesting ladders were brought into the cave for final placement.
Cremation before deposition of remains in caves was apparently rare, based on the small number of burned human bones fragments found so far. There is a mix of bones from adult males and females, and from children. That, along with the absence of trauma marks, suggests that warriors were not singled out for cave burial as a particular honor.3
It is possible that placing the remains in a cave may have been used by some small villages without a burial mound, perhaps as a rare form of burial for certain kinship groups. There is not enough evidence, especially after disturbance of remains by relic hunters and vandals, to determine if the graves reflect burials of people with inherited (ascribed) status, or of individuals who had achieved status.
If a site includes prestige goods associated with men, women, and children of all age groups, then it could be interpreted as the family grave of a hereditary chief. All members of such a family would have ascribed status due to their kinship status, even the children. If prestige goods are associated with young men or mature adults, without any skeletons of children, then the gravesite may be the final resting place of just those individuals who had accomplished something special in warfare or in the life of a community.4
The social status of people buried in limestone caves in Virginia is not clear. No identifiable artifacts were found that associated Virginia's mortuary caves with just the elites or with any particular clan. There is not a clear enough pattern to state whether the caves are sites of those with inherited, or with achieved, status.
