I found this metal about 4" underground at a site in Dartmouth near where the Halifax Explosion occurred. It certainly appears like it was stressed from some powerful force, but was it from the explosion. The actual ship was blown apart and most of it's hull likely vapourized in the actual explosion however, some debris has been found over the years. This piece is bowed out, narrowed at the curvature, and has a hole in the centre which is also fragmented and warped in the same direction. The only thing that puzzles me is the "squareness" of the piece. Perhaps someone with some knowledge of metalurgy could help me to figure out if this could be from the explosion, or just a hunk of metal cut away and discarded. Once again, thanks to all who help me in this pursuit.
