Schist Happens: How I Fell In Love With A Bunch of Rock

So....black...

So….black…

It’s black–black as tar-covered ravens in a coal mine at midnight. It’s shiny. At river’s edge, it’s fluted into perforated columns I wanted to climb into.

This was, of course, impossible, because A) I was paddling past the schist with 6 other people, and B) since the air temperature was around 115 degrees, the schist would have branded me all over.

There's even a word for that shine: "schistocity."

There’s even a word for that shine: “schistocity.”

Talk about a metaphor that rocks!

There are other rocks in Grand Canyon to love, and I will write more about them in the coming days. But right now I’m still reveling in the memories of that sleek, black, geological poetry.
