Today my family went to Cuyahoga Valley National Park in Ohio. My favorite part was the Ledges. There was bright emerald green moss on the rocks and cliff edges. We hiked through a cave called the Ice Box. I learned that the Cuyahoga River has caught on fire many times! It was so dirty, that it actually burned.
The fire in 1969 inspired Earth Day, the Evironmental Protection Agency, and the Clean Water Act.
Wow! Dirty water!
