Studying the sediment of a mountain river can reveal thousands of years or more of a waterway’s history, including new threats from more frequent wildfires and increased precipitation brought by climate change. Understanding those challenges may provide insight into other waterways, including urban streams like the Cuyahoga River in Ohio, named River of the Year as it marks 50 years since the 1969 fire.
