Just before Christmas, Brandon and I received a letter from Rich, at the Smithsonian, which provided us with some preliminary information on the gravesite:
The burial surface is a large shallow depression in the soil located on a steep slope. The depression is approximately one foot deep. The western side of the burial depression, presumably the head, is marked by two small rock cairns that feature natural upright stone slabs projecting from the tops. The opposite end (foot) is marked by two small rock cairns.
The burial appears to be shallow when probing in the deepest part of the depression, with the burial shaft floor located at a depth of approximately 2 feet.
The shaft is of sufficient size to have accommodated two persons lying side-by-side. It is very shallow, but this may have been due to haste during excavation of the burial pit, or it could have resulted from termination of the efforts of the grave diggers when they encountered the underlying siltstone strata.
Two items that could effect bone preservation were noted: oak trees are in the vicinity of the burial, and the tannin from these leaves can elevate the acid content of the soil; and the presence of some white clay also indicates soil acidity. However, the burial is on a steep slope and located high up near the brow of the ridge. The slope and wind action at that elevation could retard a significant accumulation of leaves. The slope also prevents any significant amount of water from collecting in the burial depression.
The remoteness of the burial site will make it necessary to complete the disinterment in a single day or else provide overnight guards.
