Cascade Milling Company

The Cascade Mill, the lesser-known original mill in early Sioux Falls, was built before the more famous Queen Bee Mill, completed in 1877. It was smaller and less expensive, located upstream from the falls on the east side of the Big Sioux River. Made from native quartzite stone, it was robust enough to withstand early floods that damaged other structures. The Cascade Milling Company began producing flour in 1878, connecting to major railroads for distribution. Despite challenges like limited grain supply, the mill exemplified the entrepreneurial spirit of early Sioux Falls and contributed to the city's industrial development.
