This discussion seems to have bifurcated in two directions away from
the original question.
Some of the discussants have carried the ball away into a discussion
of federal preservation policy, which doesn't really relate to the
question that came, I believe, from Australia.
Other discussants have produced input that relates to the actual
research value or preservation of temporary military buildings, which
I thought was the issue. This is why I brought up the specimens in
Iceland, which is a convenient spot for locating and studying them.
