Adam, Mike, & everyone,

This is a significant subject, partly in that there is
a bunch of misinformation regarding new Campos on
Ebay.

I spent last winter in Chile and Argentina, and
although I did not visit Campo del Cielo, I did spend
time with the family on who's land the principal part
of the strewn field is located.

They affirm what Adam's respondents have reported:
there is no "new" area on a mountain side. The "new
Campos" are indeed simply from greater depth in the
exact same area as the "old" Campos.

There is a reason for the inaccurate claims to the
contrary. The strewn field is mostly in the Chaco
province which has enacted legislation making export
illegal. However, the strewn field overlaps the
province boundary into the adjacent Santiago del
Estero Province which currently has no such law.

As a result, to reduce chances of legal problems,
exporters are claiming that their material comes from
a "new" area in Santiago del Estero---essentially
equivalent to saying "the fossils I am selling come
from private land just outside the National Park
boundary".

Cheers,
Norm
