That profile of the cellar in Southern Maryland would be a spectacular
museum exhibit. The problem is not the technology of preservation, however,
but museum planning and long term commitment.
 
While a project is still fresh in everyone's mind, the idea of preserving
site features for "posterity" is very attractive. Ten, twenty years down
the line, entropy sets in, the profile deteriorates, interest falls off,
and finally the damn thing is in the way.  This sort of enthusiasm led
Delaware to build Island Field museum in the middle of nowhere. Times
changed, exposed burials became politically unfashionable, and the state is
saddled with a roofed-over sacred site they can't abandon, with inadequate
artifact storage and very difficult management problems.
 
A scale model, or a life-size photo mural, would be much more practical
than a preserved in situ  profile. If you want to preserve a section for
posterity, why not simply lift the visible artifacts into some kind of
frame?
 
The real problem with preserving the profile might be the fact that you
wouldn't have access to the artifacts for analysis.
