I haven't seen the Smithsonian article (I know which parts were used
in the CSICOP piece because the author spelled it out; the Smithsonian
article is dated Vol. 19, No. 3, 1988), but I've read Oak Island has a
fairly unusual geology. It's reportedly covered with a considerably
thick mantle of glacial till, which is very tough, and 167 feet or so
deep there's a bedrock of anhydrite -- I suppose meaning limestone,
gypsum, sandstone and shale -- which is weak and water soluble. What I
know about geology would fit in a mosquito's pocketwatch and leave
room enough for George Bush's brain, but this suggests to me that
where the mantle was fractured it could become unstable and drop into
the bedrock, though given the thickness of the mantle such a fracture
may be unlikely to occur naturally. The sinkhole theory, though,
requires that diverse materials were dropped into a deep hole over an
extended period of time and were gradually buried by naturally
occurring debris. It's surmised this would have all happened in the
space of about a century. One might expect that the nearby pit which
caved in in 1878 (also considered an entirely natural phenomenon by
the CSICOP article) should itself have filled in with debris by now.
