5 year-old Marshall Hayum discovered a 4,000 year old Native American plummet on a nature walk with his school.
“It looked like a bomb,” Marshall said. “So I picked it up.”
According to Concord Museum Director David Wood, the “bomb” is actually called a plummet. Although not much is known about plummets, Wood said the prevailing theory is that they were used by Native Americans to weigh down their reed-woven fishing nets.
Finding plummets was a common occurrence among farmers in the 1800s as they turned over the soil, he said. Over the years, however, as more and more were found, plucking plummets has become a much more difficult task.
