At first glance, a huge steel ball sitting quietly in a creek or wooded area might look like nothing more than an unusual piece of scrap metal.
But objects like this can have a remarkable story behind them.
This enormous steel sphere was once associated with the powerful machinery of industrial grinding mills—machines built to reduce hard materials such as minerals, ores, and other raw substances into much finer particles. What now appears to be a weathered relic was once part of a noisy, demanding industrial process that helped supply materials for a rapidly developing modern world.
It is a fascinating reminder that some of the most important pieces of industrial history were never famous. They simply did their jobs, day after day, until their usefulness came to an end.
