Illinois' State Fossil, the unique and bizarre Tully Monster was first found in Mazon Creek. Grundy County Speedway is located in Morris. Grundy County is also home to Dresden Generating Station—the first privately financed nuclear power plant built in the United States—and the Morris Operation—the only de facto high-level radioactive waste storage site in the United States.
Grundy County was established on February 17, 1841. It was formed out of LaSalle County and named after U.S. Attorney General Felix Grundy (1777-1840). The county was well known for its coal mines and attracted miners from Pennsylvania and other regions to work its deposits. Braidwood endured one major coal mining disaster. Most of the coal was destined for the Chicago area.
