Ancient Metal Hammer. In June of 1934, members of the Hahn family discovered a rock, sitting loose on a rock ledge beside a waterfall outside London, Texas. The site primarily consists of Cretaceous rock (75 to 100 million years old). Noticing that this weathered rock had wood protruding from it, they cracked it open, exposing the hammer head. To verify that the hammer was made of metal, they cut into one of the beveled sides with a file. The bright metal in the nick is still there, with no detectable corrosion. The unusual metallurgy is 96% iron, 2.6% chlorine and 0.74% sulfur (no carbon). Density tests indicate casting exceptional quality.
