The term "Cuyahoga" primarily refers to the Cuyahoga River, which flows through northeastern Ohio. It is known for its historical significance, particularly its role in the industrial development of the region. The river runs through Cuyahoga Valley National Park, a protected area that offers recreational opportunities and scenic views. The name "Cuyahoga" comes from a Native American word meaning "crooked river." The river gained national attention in 1969 when it caught fire due to pollution, highlighting environmental issues. This event contributed to the modern environmental movement and the establishment of the Clean Water Act.
