[meteorite-list] How to document and preserve the crater at Caranas?

[drtanuki]

List,
  The Caranas crater needs to be photographed from the
air with a high resolution camera and a stereo-pair
should also be made.
  Secondly, if the crater is to survive any rain
thought should be given as to how it could be
preserved, with low tech and cost in mind.
  Are their any plastics or cement compounds that
could be sprayed over the crater that would work? Or
should a plastic cast of it be made to at least have a
full-sized replica?  If Peru wants a National Landmark
and tourism to the site they need to take some kind of
urgent action so that they have more to show than a
mud hole full of trash.
  Any thoughts or ideas?
