The Yellow Boy story (see previous post) is not all bad, though. Some companies are addressing the problem by reclaiming the iron oxide with a process known as bioremediation  The process cleans the site and gives the company or affiliated companies a substance that they then sell as pigment for concrete pavers and other applications. . . . The boulder sitting atop the shale in this photograph is granite, a glacial erratic brought down from Thunder Bay or points north by the last glacier in this area.
