Thanks for the information. I have been trying to follow it. I had just
been reading "Vikings in Ireland and Scotland in the Ninth Century"
by Donnchadh Ó Corráin, Department of History, National University of
Ireland, Cork (ISBN 2-503-50624-0) and there is references from the
Cologne archive that place the Vikings from the "kingdom of Lothlend,
Laithlind or Lochlainn" there sometime between 825-859 CE. An
important archive that will be missed for some time, and in part forever.
I found the animation of the disaster informative as it showed how it
could have led to a greater loss of life if not for the quick thinking of the
workers in the subway tunnel who perceived the impending disaster,
stopping traffic and alerting those working in the archives on the
surface.
It seems hydrostatic pressure has caused the slip and fall of what we
here sometimes call a "slurry wall" which I've worked alongside the
construction of by a French firm back in 1984 while in urbban
archaeology in New York City. A water displacing bentonite "slurry" is
pumped through a channel dug to whatever base, in bedrock, chiseled
into, rebar cages lowered and concrete pumped displacing the slurry
monitored for content, filtered and recharged a section at a time. It
apparently was used in the World Trade Center so-called "bath-tub"
design and the former US Federal Assay Site, recently sold as the most
expensive property in Manhattan, per square foot, two blocks from the
East River, NYC where a large crew recovered over 1 million artifacts in
1984.
Personally terms such as "bath-tub" and "ground zero" do nothing for
our field often a part of tourism to the original significant sites these
terms come from, in my opinion, once working in the now demolished,
could have saved it's facade building on Trinity Place nearby and for the
firm which conducted the orginal archaeology survey of the US Army's
Fort Drum, NY in 1983 once located in the 90s of floors of the WTC,
tragically struck on Sept. 11, 2001.
By the way an 18th horse harness was recovered in the orginal
construction of Building 7 there and is conserved at the Long Island
Science Museum, NY. The towers construction had seen a ship hulk in
landfill and later when I accompanied archaeologist Edward
Johanneman, MA to Building 7 to look further, we were denied access.
