BRECKSVILLE, Ohio (AP) — A national park that protects about a quarter of the Cuyahoga River is preparing to celebrate the river’s health 50 years after it infamously caught fire.

A ceremonial torch traveling the length of the 85-mile-long river will make a stop in Cuyahoga Valley National Park on Friday afternoon on its way to Cleveland.

The public event comes one day before the 50th anniversary of the June 22, 1969, fire. It will feature the passing of the Xtinguish Torch Fest torch along with music, poetry and the unveiling of a new sculpture.

Speakers, including a regional director of the National Park Service, will outline efforts to restore the river from its abysmal earlier condition to a vibrant place for wildlife and outdoor recreation.
