Steel column fragments, known as Tridents, recovered from Ground Zero. Miscellaneous building materials are attached to the column, including welded wire fabric, steel straps, and concrete.
These two steel columns once formed part of the exterior structural support of the east facade of 1 World Trade Center (North Tower). Welded to box columns at bedrock, 70 feet below street level, these columns branched at the fifth story into the three prongs that give them the name tridents.
