石头城
Stone City was founded in 1850 along the banks of the Wapsipinicon River. Early settlers discovered dolomite and limestone at the location. In its earliest history Stone City was known as the Anamosa Quarries. Later the area became known as the Stone City Quarries. In the late 1800s, Henry Dearborn, John Green, and John Ronen each opened limestone quarries in the area. As the railroad system expanded westward, distribution of limestone to bordering states increased. Stone City limestone became the primary building material for railroad bridges, bridge piers, and foundations for major buildings. Each year, between the years 1859 to 1895, over 150,000 railroad car shipments of limestone were sent from Stone City.
