What is the Name of this Waterway?

Last weekend, I took my daughter Aviana on a drive around town. She’s a Class of 2020 senior, and a little bummed about missing all the fun of her last year of school. But this cheered her up. I told her I knew about a secret pathway. It’s right along this waterway which I CANNOT REMEMBER THE NAME OF! Seriously. It’s been a few days and I still don’t remember? Cottonwood Flume? Maybe? Help.

Anyway, we had a nice stroll.

The moss patterns along the water look like art. Or a map.

Aviana had asked me why there were holes along the path. The answer popped up on its own.

She thought it was cute.
