Utah's Fallen Warrior Memorial includes an artifact from the World Trade Center: a 9000-pound section of the slurry wall, whose main function was to hold back the Hudson River from flooding the basement of the World Trade Center. When cleanup began at Ground Zero, a section of the slurry wall had to be removed for new rail lines, and a contractor sought to preserve this section and convert it into art for a memorial. Artist Sandra Priest was commissioned to sculpt, sand, and polish these pieces of artifact. The basement had been bounded by a 3,300-foot-long, three-foot-thick slurry wall, or perimeter wall, constructed from grade and socketed into bedrock at depths of as much as 20 feet. In the 1950s, continuous underground walls were built using bentonite slurry as temporary support for slot excavations in difficult soil conditions, and the Port Authority Engineering Department recognized early that this technology would be suitable for constructing a safe, economical deep basement in extremely difficult ground conditions. The slurry wall was installed over a twelve-month period ending in 1968. The memorial site was dedicated on October 31, 2013 by Utah Governor Gary Herbert, and Dave and Raette Belcher provided this historical artifact.
