Michigan Historical Marker
There is a Michigan historical marker at a viewing point at the site of Michigan Limestone and Chemical Company that reads:
| “ | Limestone is a mineral raw material essential in making steel, chemicals, and cement. Henry H. Hindshaw, a geologist, established in 1908-09 the commercial value of this area's limestone for industry. The high purity of this deposit and the availability of water transportation led to the development here of a port and quarry. Both are named Calcite, after the principal ingredient of the stone. The Michigan Limestone and Chemical Company, founded in 1910, began operation in 1912. Purchased by Carl D. Bradley and the United States Steel Corporation in 1920, the company came under the ownership of U.S. Steel upon Bradley's death in 1928. In 1951 the company became a division of the corporation. Self-unloaders of the division's Bradley Transportation Line carry limestone from this, the world's largest limestone quarry, to industrial ports around the Great Lakes. | ” |

Famous quotes containing the words historical and/or marker:
“Reason, progress, unselfishness, a wide historical perspective, expansiveness, generosity, enlightened self-interest. I had heard it all my life, and it filled me with despair.”
—Katherine Tait (b. 1923)
“Personal change, growth, development, identity formation—these tasks that once were thought to belong to childhood and adolescence alone now are recognized as part of adult life as well. Gone is the belief that adulthood is, or ought to be, a time of internal peace and comfort, that growing pains belong only to the young; gone the belief that these are marker events—a job, a mate, a child—through which we will pass into a life of relative ease.”
—Lillian Breslow Rubin (20th century)
